What is easier to get, a pass rush or a "franchise" QB?
The answer is a pass rush because it can be had from any number of sources. My arguments for avoiding Suggs are based on my opinion of his very high bust potential and also the standpoint point that pass rushers will be available in round 2 for sure and some have indicated Peek could be had all the way in round 3. While I still want Newman to go with DL picks in rounds 2 and 3, if Newman is gone and Leftwich is sitting there, smart money says take him because Blake won't play for more than a couple years.
A pass rush can be had simply with the same personnel if the DC gets some balls and forces things to happen by way of blitzing (my biggest pet peeve of last year). If you are going to fail then go down swinging and go down being aggressive. They went down being just about as passive as they could which made the defense look worse than it probably really was in reality.
A QB can change any single game in which he plays. It is very very rare that a DE can and Suggs, IMO, will not make a difference in every game he plays.
