Davis was easily the best player on the board and it would have been a huge mistake to have passed on him. If you follow the theory of drafting by tiers, Davis was in a different tier from everybody else available at 13.
I think the 2007 Raptor team's biggest problem was a lack of secondary scoring option. We had Bosh (who was neutralized by Mikey freakin' Moore), and everyone else. Was any team scared of Calderon or Parker dropping 25? Definitely not.
This year, we've got 2 legit scorers in Lowry and DeRozan, and even Salmons and Vasquez have the ability to turn a broken play into 2 points. I'm not suggesting this current team are worldbeaters, but their offense isn't as one-dimensional as the 2007 team, without even saying anything about the improved defense.
