We're back where they should you 49ers and show all the tears calling -- last season what's it stout defense against the run but so far this season. That's skill set hasn't been overly necessary. As Dave Feldman explains all that will change this week where -- trip to Minnesota. Adrian Peterson is not your typical NFL running back he's bigger stronger and faster than your average ball carrier he can run around you or he can run through you. Pick your poison. He also recovered from a devastating knee injury like it was nothing. Fun facts that don't seem so fun to 49ers defensive coordinator -- fans you. Still has his great speed and cutting ability. And I'm sure that they'll get better and better. As he goes throughout the season you know we won two weeks really was better and I'm sure we better week to week three. Three years ago the 49ers went to the metrodome with a two and oh record. The 49ers had the lead until the final seconds when Brett Favre worked his magic the coach of that 49ers team was Mike Singletary. Who's now linebackers coach for the Vikings. What's in those days nor does the way there they wanted to break I mean that's that's success you know on -- -- of prisons are -- would have liked his doing that in. How messy there it's us you know Flynn. We're no different amateurs -- -- -- -- -- -- more than you know -- -- whether it was a pretty severe or close you know we're going oh very little one my focus only. No woman very. There is opposing coach and particularly go opposing coaches. Just precludes him. On the injury front Brandon Jacobs still isn't ready to play. He told me on Thursday that his injured left knee is improving but he's rehabbing batter but he still has no timetable. On when he'll be able to play again he said it's very difficult. Watching the team this good from the sidelines but he added I need to be a 100% when I get in there so I don't get injured again. In Santa Clara with the 49ers. Dave Feldman Comcast sports net. If the first two games of the -- season and shown us anything it's an Alex Smith has graduated from a game manager to a game maestro the 49ers give him a lot of responsibilities in conducting an orchestrating. That offense such as going up to the line of scrimmage and checking out a run play to a pass play or from a pass play. To a run play and I kind of communication is going to be typical Sunday and allowed dome against the Minnesota Vikings. Alex Smith ranks second in the NFL in passing efficiency but those numbers don't tell the whole story he's also a big reason that Frank Gore has gotten off to a very good start.
