I'm a fan of taking Moultrie, too, but I think he'll be long gone by the time the Cs picks roll around. Right now, they'd be 23 and 24 ([dang] Clippers keep winning games). I don't see Moultrie dropping past 20.
http://insider.espn.go.com/nba/blog/_/name/nba_draft/id/7823302/2012-nba-draft-dion-waiters-arnett-moultrie-stocks-risingFord notes that "A sizable group of scouts and execs think we have two players ranked too low on our Big Board: Syracuse's Dion Waiters and Mississippi State's Arnett Moultrie." As a result, he moved Moultrie up from 19 to 16 (jumping over Meyers Leonard, Kendall Marshall, Tony Wroten and Terrence Ross), and Waiters from 21 to 15 (jumping the same guys, Royce White and Moultrie).
If the picks are down at 23 and 24, I wouldn't mind Danny moving up to get the right guy, if he thought Moultrie or Leonard was a top 10 player available around 15-18. But I don't know if Danny would give up two picks to do it.
Basically, bringing it back to the topic, Festus Ezeli is not a guy the Celtics are gonna pass up somebody like Moultrie for. It's more looking at prospects in the 21 to 35 range and deciding whether you'd take Ezeli's size. On Ford's "Big Board", that means Fab Melo, White, Jeff Taylor, Moe Harkless, Marquis Teague, Andrew Nicholson, Draymond Green, CJ Leslie, Doron Lamb, Evan Fournier, John Jenkins, Ezeli, Tyshaun Taylor, Scott Machado and Will Barton. I'd prefer White, Nicholson, Green, and Leslie at least. And I think Machado will be a decent backup point guard in the NBA for what it's worth, and I'm more confident Lamb will have a career than Ezeli (or Melo). I think Ezeli's a guy you take at the very end of the first round or early in the second. Even though 24 isn't that great a pick, I think they can do better there.
