No matter what Noah does this year for the Bulls, Chicago still did the right thing by passing up on Hawes because Paxson found equal (if not better) value in Aaron Gray, who fell into Chicago's lap halfway through the second round.
Halfway through the season Hawes and Gray have played nearly identical minutes (slightly over 250 minutes each), but Gray seems to have proven the more solid professional thus far, doubling Hawes's scoring average and topping him in nearly every other statistical category as well. Perhaps the most glaring difference is in field goal percentage, where Hawes is averaging 39% and Gray is averaging 51%.
Some may argue that with a semblance of an outside shot and plenty of potential, Hawes is a better long-term option, but shooting 2-11 from long distance this season hardly can count as a persuasive argument. Hawes would've been brought to the Bulls to score down low, and that's something Gray really hasn't had much trouble with so far.
