I'm rather excited about him. David Thrope recently ranked the sophomores and had Sully #4 behind Davis (picked 1st), Drummond (picked #10) and Lilliard (picked 6th). It's an insider article, but I think he had Terrence JOnes (picked #19) as the 5th ranked sophomore.
If we're talking steal of the draft... it's possibly Drummond. He was thought to have arguably a higher ceiling than even Davis and slipped all the way to #10, because of some questions. If he fulfills his potential, he's going to be a dominant franchise player.
In retrospect, that 2012 draft might be a lot better than we thought. Anthony Davis has been RIDICULOUS so far this season. Statistically, he's been the 4th best player in the league behind Kevin Love, LeBron and CP3. Davis is only 20 years old... he's the second coming of Kevin Garnett (or perhaps Duncan). Davis is outperforming KG at the same age. 20 points, 11 rebounds, 4 blocks, 2 steals on 50%/84%
