According to Derrick Green, via TomVH (information is on the Wolverine Nation forum, LINK), the coaching staff does intend on taking one more RB. I figured we'd leave a spot open for a guy like Isaac anyway just because of how special a talent he is, but I like that we're aiming for a 3rd back, regardless whether it's Isaac, Green, or someone currently not on the radar. We need the depth, we need the talent, and you can never have too many skill players.
Not sure how this will impact the rest of the recruiting class, but I have to think at some point there will be more focus on DT. Fingers remained crossed for Poggi.
