I thought this was an interesting, if dubious, article by Pat Caputo. He argues that the Lions would be better served drafting a guy like Berry or Derrick Morgan over Suh. The premise is that the Lions need playmakers, Suh is smaller than you would like for a DT, and isn't necessarily a great fit for the system the Lions will employ. FTA:
Suh gained his greatest recognition by dominating the Big 12 championship game against Texas. But in that game, he was not facing nearly the same caliber of player he will see in the NFL.
(My counter is that nobody in college plays against NFL starters every game, but Suh was dominant in games against Oklahoma, Texas, VT, and the rest of the Big 12. At some point, you have to accept that some extrapolation is necessary.).
While I do agree that the Lions need help on defense, Suh had one of the most dominant seasons in recent memory for a DT, and did so against top-flight talent. Sure he has some flaws, but so does everyone else in the draft. All great teams, though, are strong on both sides of the line, and the defensive line for the Lions last year was laughable for most of the season. I'd take Suh in a heartbeat and then nab a combo lineman/LB in the second or third round if you are so worried about a pass rush.
