Die Jäger des Schicksals » physics and positioning, sometimes they

Next time you are watching a game and think to yourself, that was a bad goal, the goalie has to have that shot, you may very well be 100 per cent correct, but you also may be completely wrong, based on some underlying factors. Keep in mind a few things that are true when it comes to goaltending; physics and positioning, sometimes they both factor in to make a shot literally impossible to stop. I was doing colour commentary for the Pittsburgh-Ottawa game the other day and on the winning goal with under two minutes left that beat Craig Anderson, (a slapshot from just inside the face-off dot by Christian Ehrhoff), there was a defensive breakdown that allowed Ehrhoff to walk right downtown, tee it up and hammer it top shelf. Anderson did what he could to play the percentages on the shot, going into the butterfly, staying upright, and trying to make himself as big as possible. He was beaten by a great shot, but he also really had no chance to physically stop it if it didnt hit him. I have been working with a brilliant physicist named Alain Hache (who is the author of the Physics of Hockey) and he has done some terrific work regarding the science of the speed of the puck coming at goalies and the subsequent reaction time they have to make the save. I have tried to pick his enormous brain as to enlighten me with the other side of goaltending and he has done a great job of helping break down some physics that come with velocity of shots. This is a general thought process, but from a reaction standpoint, the average reaction time is 0.2 seconds. Now you have to factor in the distance where the shot comes from and the velocity (how hard the shot is) to see whether there is sufficient time to react to the puck, or if positioning is the only hope for the save. Lets take that Christian Ehrhoff goal on Craig Anderson as an example. Anderson was at the top of his crease which was about six feet away from his goal line. Ehrhoff was just inside the faceoff dot and around 18-20 feet away in total distance. For this equation, lets round up and say 20 feet for clear numbers. If he shoots the puck at 80mph, which is likely based on how much time he had to walk into to it and how hard he shoots the puck (this is on the low end of how hard I think he shot it), the reaction time would be counted as this: 80mph from 20ft away = a reaction time of - 0.17seconds. So given this formula, with that shot by Ehrhoff, Anderson wouldve had 0.17 seconds to make that save, and if the average athlete reacts at a rate of 0.2 seconds, what we are seeing is a shot that was unstoppable based on sheer reaction time. Now this is where positioning factors in because if Anderson had taken some ice for himself, he would at least get an opportunity to be hit by the puck. Had the shot only been 60mph, the reaction time would be 0.23, which, in turn, is not much more time for Anderson to read/react, but if he anticipates and reacts properly, he at least has a chance to stop it, given he is in the same position in net. If this had been Zdeno Chara or Shea Weber firing it from there, hitting that 100mph neighbourhood, good luck. Thats where you have to hope that it hits you, because with that scenario, you only have 0.14 seconds to react to a 100mph slapshot from that distance. The scary part with all of these reaction time scenarios is that in this case, it was a clear shot by Ehrhoff. There wasnt any potential screens/tips, you didnt have to fight through bodies or legs to track the puck, you didnt have to worry about a potential pass scenario where there are options for the shooter to factor in on your depth in the crease; all the checklist things that have to be considered in that initial read of the play that a goalie has to process in a split second. Keep in mind as well when the using this formula, the distance is calculated from when the goalie first tracks the puck, meaning if the puck is shot from the point but the goalie doesnt see it until it goes by, lets say a high screen in the slot, then the formula begins with the distance between the goalie and when he first sees it, not from where the puck originates. So the next time you see a shot that goes in, and your initial thought is stoppable puck from that distance, there just may be some underlying science that factors in on the goal that helps explain why the goalie was late to react.

Barry Sanders Jersey . -- The Windsor Spitfires were left with just one goaltender Tuesday after having their starter walk out on them midway through Game 3 of their Ontario Hockey League playoff matchup with the London Knights.MILWAUKEE -- Jonathan Lucroy has been frustrated, struggling at the plate the past month despite being named to his first All-Star team. That all changed Tuesday night against the Cincinnati Reds. Lucroy homered leading off the bottom of the ninth to give the Milwaukee Brewers a 4-3 victory over the Reds. "To be honest with you, the last couple of weeks have been kind of tough for making solid contact, but Im glad to help the team out, contribute and get it done tonight," said Lucroy, who was batting just .200 (21 for 105) in his last 25 games. It was Lucroys second homer of the game and 11th of the season. It was his second career walkoff homer and both were against the Reds. His first was last season off closer Aroldis Chapman and this one was off Sam LeCure. The Brewers had lost five consecutive series before beating the Reds in the first two games of this series. Lucroys average had dipped from .341 on June 18 to .308 entering Tuesday nights game. "Hes frustrated because he thinks hes squaring up some balls," Milwaukee manager Ron Roenicke said. "Its not like he wasnt locked in, but today obviously he was." Francisco Rodriguez (4-3) pitched the ninth to earn the victory. Cincinnati, which is 0-5 since the All-Star break, brought in LeCure (1-2) to pitch the ninth. His outing lasted just three pitches as Lucroy hit a 1-1 offering for a line drive homer inside the left field foul pole. His first homer of the game was on a 3-2 pitch from starter Homer Bailey in the sixth. The Reds came out of the All-Star break just 1 1/2 games behind Milwaukee in the NL Central but have quickly fallen 4 1/2 games back. "We just havent executed," Cincinnati manager Bryan Price said. "We havent swung the bats well. We havent gotten a quality start. "And we havent played particularly good defence, weve missed some signs and just havent played terribly well," he said. Milwaukee scored all its runs on solo home runs. Ryan Braun and Aramis Ramirez hit back-to-back homers in the first inninng on the one-year anniversary of the start of Brauns 65-game suspension for violating Major League Baseballs drug policies.dddddddddddd "Im glad Im not facing them so its nice to have them on our side," Milwaukee starter Jimmy Nelson said of having Braun, Ramirez and Lucroy in the lineup. Braun hit his 13th homer and Ramirez followed with his 12th homer, and first since June 26. Cincinnati made it 2-1 in the fourth on Jay Bruces RBI double that scored Billy Hamilton from third. Lucroys first homer extended Milwaukees lead to 3-1. Cincinnati tied it 3-3 in the seventh. Nelson hit Ramon Santiago on the foot with a pitch with the bases loaded and pinch-hitter Chris Heisey hit a sacrifice fly off reliever Brandon Kintzler. Billy Hamilton then hit a soft fly ball but Zack Cozart was doubled off second base to end the inning. Kintzler, Zach Duke and Rodriguez pitched three hitless innings of relief for Milwaukee. "Kintzler did a great job, coming in with the bases loaded and no outs," Nelson said. The Reds managed only five hits and Milwaukee had six. Nelson allowed three runs, four hits and a walk and hit three batters while striking out five in his fourth major league start. "He was down in the zone and his slider was good," Roenicke said. Bailey allowed three runs, four hits and two walks while striking out three in his first start since leaving a game against the Chicago Cubs on July 10 due to right knee soreness. NOTES: Brewers 2B Scooter Gennett left the game in the fifth inning due to tightness in his right quad. Roenicke said he was day-to-day. ... Cozart left the game after being hit on the right hand by a pitch from Nelson in the seventh inning. X-rays were negative and the team said he was day-to-day. ... The Reds placed RHP Logan Ondrusek on the 15-day DL retroactive to July 13 and recalled RHP Curtis Partch from Triple-A Louisville. ... A brief rain shower caused the Brewers to close roof at Miller Park in the fourth inning. It reopened in the sixth.
