I'm loven all the ideas had about Suh or Berry. I even like Evilsmuf's trade down mantra (just don't see it happening). I think both DT and DB are critical needs for the Lions and Suh and Berry are exceptional tallent that would both provide an immediate upgrade of significance. I just think that a rush that controls the LOS and takes a second (or more) off of what QBs had last year 15 yards upfield is better than a second gainned through "shutdown" coverage. Suh, at 2 seems the best "bang for the bucks" In either case the upgrade of one of the two also makes the other significantly better.
Here's to grandpappy 4 seeing stars in the sky because of a faster rush or better coverage!
