SANTA CLARA https://www.49ersfanshop.com/Adrian-Colbert-Jersey , Calif. (AP) —of the season have been a mixed bag, with his shining moments counterbalanced by mistakes.A stern challenge awaits San Francisco’s young quarterback Sunday when the 49ers travel to Arrowhead Stadium to take on the undefeated Kansas City Chiefs.“We know it’s going to be loud,” Garoppolo said before Wednesday’s practice. “I played there my rookie year (with New England) and it was rocking. So we know what we’re in for.”Sunday’s game features an intriguing matchup of two young quarterbacks who benefited from the expert tutelage of the veterans they once played behind.After serving as a backup to Tom Brady for three seasons, Garoppolo was traded from New England to San Francisco and looked sensational in five games to close out the 2017 season, which led to a five-year, $137.5 million contract for the 26-year-old.Chiefs quarterback Patrick Mahomes soaked in all he could from Alex Smith as a rookie in 2017. Smith was traded to Washington in the offseason, and Mahomes has responded with an NFL-best 10 touchdowns so far, the most by a quarterback in NFL history over the first two games. He has yet to be picked off.While the 49ers’ defense has a challenge in slowing down the Chiefs’ high-powered attack, Garoppolo and the offense simply want to avoid the potentially game-changing mishaps that they’ve been susceptible to over the first two weeks.Garoppolo had an interception returned for a touchdown in the opener at Minnesota Dante Pettis Jersey , a play on which receiver Kendrick Bourne ran the wrong route. Garoppolo threw three picks total in that loss and Alfred Morris lost a fumble inside the Vikings 5-yard line.Then in Sunday’s 30-27 victory over Detroit, Garoppolo threw a fourth-quarter interception that would have been a game-changer were it not nullified by a Lions holding penalty.It came out later that rookie receiver Dante Pettis ran the wrong route on that play, but it was still an ill-advised throw by Garoppolo.Being on the same page in the passing game is a key to avoiding those kinds of mistakes. And good communication can be a challenge when dealing with the crowd noise at Arrowhead.“I think it starts with the week of practice,” Garoppolo said. “We want to go out there and be perfect on every play call — how we hear it, how we communicate with each other between series, all that stuff. It’s a lot of little things coming together.”The 49ers hope for the healthy return of veteran receiver Marquise Goodwin, who missed Sunday’s game because of a bruised thigh. Goodwin practiced Wednesday for the first time since that injury, but he looked to be holding back a bit while running routes during the portion of practice open to reporters. Goodwin declined to speculate on whether he would play against Kansas City.NOTES: Linebacker Reuben Foster was added to the 49ers active roster after serving a two-game suspension for violating the NFL’s policies of conduct and substances of abuse. Foster is expected to start at inside linebacker against the Chiefs, but coach Kyle Shanahan was non-committal about whether rookie Fred Warner Jimmy Garoppolo Color Rush Jersey , who has been a bright spot through two games, would remain in the lineup if Foster starts. Offensive lineman Matt Tobin was released to clear a roster spot for Foster. … Strong safety Jaquiski Tartt (shoulder) and guard Joshua Garnett (toe) did not practice. Goodwin was limited as was cornerback Ahkello Witherspoon (ankle) and guard Mike Person (foot). He dropped a spot from last year’s ranking, but Kyle Shanahan stillmakes the first half of head coaches."WhiteFanposts Fanshots Sections 49ers Salary CapLevi’s Stadium Events49ers Transactions49ers Injury News49ers Press Conferences & Conference CallsRotoworld head coach rankings ask if Kyle Shanahan can find “it”New,48commentsHe dropped a spot from last year’s ranking, but Kyle Shanahan stillmakes the first half of head coaches. PDTShareTweetShareShareRotoworld head coach rankings ask if Kyle Shanahan can find “it”The San Francisco 49ers were thought to be having a big push in 2018 with the rise of Jimmy Garoppolo and their strong 2017 finish. That didn’t exactly happen. They lost Jerick McKinnon before the season started and Garoppolo three weeks into it. At the end, the 49ers were holding on trying to get out of the season with as few IR-designations as possible. But now we’re in March and it’s time to see how Kyle Shanahan ranks as a head coach. Rotoworld columnist Patrick Daugherty did his yearly rankings and this year Shanahan goes back one spot from 14 to 15. The top five were Bill Belichick, Andy Reid, Sean McVay, Doug Pederson and Pete Carroll. Here’s what Daugherty said about Shanahan: I think that sums everything up. Honestly https://www.49ersfanshop.com/Fred-Warner-Jersey , 15 seems pretty generous given some of the things that happened this season. I do think Shanahan is the answer and was dealt an awful roster as opposed to how Jim Harbaugh had success immediately when he arrived or Sean McVay with the Los Angeles Rams. This was put together on March 7. The 49ers had not yet gone into the free agency madness where they acquired LB Kwon Alexander, edge rusher Dee Ford, and WR Jordan Matthews. It remains to be seen how all this works and if it can have the defense get an upgrade and actually finish a game (something they couldn’t do in 2018). How do you think Shanahan ranks on this list? If the 49ers have another season like 2018, how far do you think he falls? While 2018 was something beyond anyone’s control, if the 49ers have another season like this, no front office/coaching staff is going to be able to keep fronting excuses.
