have been a mixed bag Y.A. Tittle Jersey , 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, 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 http://www.49erslockerroom.com/authentic-jerry-rice-jersey , 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 鈥?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, 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).___Report: Rams were going to trade for Mack, trade him at the end of season The Los Angeles Rams notched their first win on Monday Night Football http://www.49erslockerroom.com/authentic...epernick-jersey , beating the Oakland Raiders 33-13. The Raiders defensive front had issues andsorely missed recently traded pass-rusher Khalil Mack whom they dealt to the Chicago Bears for a couple draft picks. ESPN’s Adam Schefter reports the Rams were trying to get Mack as well and then trade him at the end of the season to recoup the draft picks. Several teams were interested in Mack’s services, the San Francisco 49ers included. It was obvious securing Mack wouldn’t be cheap in draft capitol and would get worse when contract numbers got discussed. The Rams still have players like Jared Goff to extend, which at least makes the thinking process understandable, but still crazy. It was already known the Rams tried to trade for Mack. The Raiders declined a trade offer from the Rams due to fears the Rams would, “pick too low.” IE; the Rams would have a good season and the first rounders the Raiders no doubt would have received would be used in the tail end of the round. The Rams have been spending money like crazy in anticipation of 2018. They extended Todd Gurley, traded for Brandin Cooks, and backed up the Brinks truck for Aaron Donald. Adding Mack into the mix, along with that contract he received from the Bears, easily could have put the Rams into future salary cap struggles. This might have been the only way to get him. So all of that for a one-year rental. And it’s quite an assumption the Rams could get their picks back on the huge contract they’d no doubt sign him to. They probably could, but it’s still a risk.The Rams already traded draft picks for Cooks and would be risking more of their future for Mack. Failure to get their investment back would hurt their future. On the other hand Womens Ahkello Witherspoon Jersey , if that trade went through and the Rams got Mack, only with the intention to trade him after 2018, this could have been the most expensive Super Bowl all-in ever seen. In any case, the Rams clearly lost this battle in the arms race. If Monday night is any indication, they definitely could have used Mack. The Rams, with Ndamukong Suh and Aaron Donald on the same line managed just one sack against the Raiders. Who knows what the addition of Mack could have brought. It’s good for 49ers fans at the very least.
