Ok, actually I dont think he will be a bust, but with such high expectations he could be a major disappointment.
You say Suh is the best DT to come out in the last 10 years?? better hope its the last 20, if Suh is drafted with the number one pick, he will be just the 7th DT drafted first overall since 1936 , and the first since 1994= Dan Wilkinson
2nd if Suh is drafted with the first pick, he will be the 2nd HIGHEST PAID DT in the league after Albert Haynesworth, who is listed as 6'6 and 350 vs Suh 6'4 305, Suh wont throw around 320 pound NFL guards and centers like he did at nebraska, or like Haynesworth does now.
3rd much like Mario Williams was thought to be a major mistake until both Reggie Bush and Vince Young's failures, if EITHER QB Bradford or Clausen becomes the next Joe Montana, it wont matter if Suh becomes the next Reggie White, he will be considered a mistake.
4th I see 5 DTs (Suh, McCoy, B. Price, D. Williams, Cody) plus college DT likely moves to NFL 3-4 DE (Odrick) all drafted in the 1st round. With alot of value in the later rounds (Arthur Jones, Lamarr Houston, Tyson Alualu, ect) the point being four years from now there will be alot of competition for who is the BEST DT to come out of this years draft class, and certainly McCoy and someone COULD end up being better Pros, even if Suh was better in college.
