I think RG III is going to be very successful in the NFL. I don't know if he'll be worth 3 one's and a two but very few players are. To me, he's only a bust if he falls well short of the normal expectations for a guy drafted with the 2nd pick. Barring injury, I think it's almost impossible for this guy to go bust. He has all the measurables, he can make all the throws, PLUS he has integrity, work ethic and he clearly understands the game. If I were picking for the Colts, I'd draft him ahead of Luck and I consider Luck to be one of the safest picks ever. I just think Griffin's ceiling is higher.
My bust pick would be either Coples or Poe. I know a lot of people are high on Kendall Wright and while I wouldn't call him a bust, I don't think he'll be anything special at the next level. Tannehill would be a gamble in the third round, so if someone takes him before that he'll headline the bust group.
