Detroit's defensive lineman navy -- seen four from last year for the 49ers expect it being much different the defensive front this Sunday. This is their -- more -- and I think their loved. You know the more experience -- there to work familiar together so they're more forward to each other. Still a great quickness and speed of -- line energy lineup and different configurations. You know of their pressure more -- the blitz you more. So you got to be ready for -- and you know I think it's really added to there profile. But Greg Roman is always adding to the 49ers profile as well. Constantly creating different offensive formations he rolled out and you went against Green Bay. Walking up the blocking by putting Leonard Davis and Daniel Kilgore in new positions. Love this is new on a good. Tight end position -- but none of them four of those tough. There's no touchdowns and at times. Get in there and personnel and didn't used to. The angles because that's most different -- where I am as senator so. It's an engine Kilgore played a wing back for the first time ever be effective this super sized package is obvious. It's. They want -- but the defense that they Leonard goes up by himself but. You know more importantly you know instead answers and I physically quality of the -- through things of that whole formation brings this is the fact that we're there trying to -- -- there to play him. And in -- I really deviate from anything and our mentality is and trust office. Roman didn't want me to reveal how many new formations he's creating UC Davis and Kilgore -- -- strains that will be sure to see more of them against Detroit. The Lions defensive front had four sacks in their game one win three of them by their starters in Santa Clara named -- Comcast sports then.
