In the 20s, I think there's probably about a 10% chance of drafting a player who will eventually deserve a contract that pays at least $10m/year. The supposed depth of this draft suggests that the possibility is probably greater than 10% and if Ainge is an above-average talent evaluator, there could be a 25% chance that the Celtics draft at least one such player if they use both picks.
Ainge could come away with two guys who are borderline starters of the same caliber as Brandon Bass, but if there is a future near-max guy (who deserves the money) who slides to an even later draft slot, Ainge will be criticized by some people around here for missing a potential building block when he should be praised for exceeding expectations.
On an unrelated noted, ESPNBoston is reporting Atlanta as a possible team that may have promised to draft Royce White, but the link is to an Insider article.
