Okay, a lot depends on whether Pablo Prigioni, K-Mart and J.R. Smith stay (we're presuming that Chris Copeland WILL stay), or whether Marcus Camby decides to retire. What clearly was missed in the playoffs was rebounding, shot-blocking, muscle. In other words, more K-Mart. Tyson was feeling sub-par, and he's more a finesse player anyway. It was Indiana's bulk that won the day.
So the Knicks need a muscle guy, an enforcer, a protector, a Charles Oakley-type who ensured that anyone getting in the way of Patrick would feel it. Somewhere, the Knicks have to pick up someone who ensures that Melo, Tyson and the rest don't get damaged--or else!! In the draft, my choice would be Richard Howell first off. But then again, such players are out there, in free agency, the D-League, Europe, China, or just sitting at home (like K-Mart was); most of these guys are familiar with NBA defensive rotation, so that's a plus.
With Jason Kidd's retirement, the Knicks lose not just a point guard, but also a 2 guard. So someone who can handle both positions, as well as being a defensive presence like J-Kidd (think of all his steals), would be a good option in the draft. Here I like Branden Paul, Jamaal Franklin, Erick Green (in that order), not sure about Tim Hardaway, Jr. Vander Blue, Tony Snell and Glen Rice, Jr. are possibilities, Reggie Bullock is a question mark for functioning at the point.
Pure point guards might be available either later in the draft (a trade for Novak???) or outside of the draft, like Ray McCallum, Myck Kabongo, Phil Pressey or Isaiah Canaan. Even Brandon Triche is not out of the question
Tony Mitchell has all the physical gifts, the question remains about his head. Otherwise he might be the steal of the draft at #24. A pure rebounder like Jackie Carmichael is also a possibility.
Center prospects might well be available after the draft, Aj. Matthews f'rinstance, or Norvel Pelle or Kenny Kadji.
So what'll it be? In the end, it all may be decided on intangibles, the personality. Since finding a rebounder/shot-blocker/enforcer may well be possible outside of the draft (remember James Singleton?), and most center prospects turn out to be projects anyway, and since a true point guard is an experience position (thank you, Pablo Prigioni), I would go for the 2-guard who can pass without too many turnovers, play defense for coach Woody. So far my choice--at this point--would land on Branden Paul.
