I think TT is active in free agency because he doesn't want to use his top picks on replacing Scott Wells and other problems. He wants his top picks to fix the defense. As far as I look at it, we need at least 2 D-Linemen(terrible D-line depth) and Center(Someone to fill in after Saturday), an OLB(Pass rush opposite of Clay), an OT (Clifton possibly gone, Sherrod still a ?) and possibly a Safety if Nick Collins has to retire. That is 6 picks right there. If he picks up free agents, that is solving a short term problem. This is why he got Saturday, and is going after Anthony Hargrove, Dave Tollefson, and possibly Demetraius Bell. He realizes he has to get big guys early in the draft and needs to fix the defense quickly. I don't think TT will trade up unless he picks up a bit more free agents because of all the needs.
