I'm not anti-Ennis. I'm anti-Ennis at #6, because I think there are easily 6 players better than him, but I don't care if they pick him either later in the lottery if our draft position changes, or with out second pick, should he still be available in the 15-17 range.
He's a good player. Our team isn't very good, and we need the best players available. If that's Ennis, so be it. Rondo shouldn't play 48 minutes every night, so if Ennis gets to play 12-15 minutes, providing much better production than Pressey while adjusting to the NBA, then our team will be better off next year. It also has the benefit of providing us with a plan B if Rondo leaves next year -- something I really hope doesn't happen, but is certainly a non-zero possibility. And if Rondo stays, that's a fine trade chip for the summer of 2015.
But not at #6. I'd say no earlier than #8, and ideally more the 10-15 range.
