The 49ers secondary plans to give Stevie Johnson plenty of attention for his homecoming. These guys. Easy rounds there the guy that goes through practice squad. Really worked himself into -- player that he is today and you know when I was there a lot as a couple you know lockers down and in you -- know how hard. He's worked to get to where he is. And his level of play nice any doubt about it knowing he is each and play. The Bay Area native is the bills leading receiver and Buffalo uses his talent by relying heavily on three receivers sets. The Buffalo's offense runs the ball as much as it passes it. And the way they do so poses a unique challenge for the 49ers that's because in those -- three receiver sets. The league's leader in rushing average CJ Spiller is also in the back field. It's extremely fast he's got 43 speed. He's lightning quick. We've got to have good edges we got to keep him and then he is really really fast the guys. Averaging close to nine yards per carry and that's that's a reflection of them breaking some big ones and he's a big play threat every time he touches the ball. Stages in the open field in a little bit like given the ball let's face it means just. Observers. So we have to be who it would have to really be. Whereas whereas I don't feel. Quarterback Ryan Fitzpatrick ran the bills formations out of the shotgun most of the time is done so effectively to the tune of a league leading twelve touchdown passes. Because he gets the ball out so quickly defensive lineman Ray McDonald says it may slow the 49ers pass -- at least initially. That's until those defensive players pick up on its Patrick's cadence and recognize some of his calls. It's Santa Clara -- by Comcast sports net. Because of the depth and the talent at the positions they play the 49ers haven't been able to get anything out of their top two draft picks. Receiver AJ Jenkins and running back Michael James and there's no guarantee that either would get on the field this season. Now they weren't able to get on the field and play. When the 49ers were without tape in. And Brandon Jake is because of injury and outlook giving Jacobs are back so that Knox Jenkins and James down another run on the latter. But that's not to say that neither of those guys don't have a role 49ers this week as they prepare to face the Buffalo Bills. James is in the role that CJ Spiller the dynamic bills running back. Meanwhile Jenkins is playing the role of Donald Jones the wide receiver who's a big play threat for the bills so even though they are competing in helping out the offense. The 49ers top -- -- are actually helping out the team's defense prepare for games this season. We got all kind. -- -- -- Mayo go on CSN Bay Area dot com right now the trick play that never was and why the offensive coordinator. Don't wanna talk about.
