I'm glad you started this thread, JT; thanks! I'm on record as being a Seth disciple here: if in top 5, try to get Wall, Evans or Favors; else consider trading down a bit and pick up an additional 1st-rounder.
You raise a titilating alternative, however. Consider two current players on teams looking to deal: the Hornets' Okafor and Golden State's Biedrins. Sure, they both have seemingly daunting 4-to-5-yr contracts currently at $9-10.5 mil. But no matter what, after next year we'll be looking for at least one stud FA -- on a new salary scale, perhaps, but we'll be shopping.
So, two (related) questions:
1) Might we be able to lure a FA in two years who will be as good or better than Okafor, or even Biedrins?
2) If our "sweet spot," in terms of maximal competiveness, is in 2-3 years, would a strategy of drafting a player in the 6-10 range (let's say Patterson) this year be preferred -- in 2 to 3 years -- to having Okafor still in his prime (and with only 2 more years on his contract at a time when we're having to renew Hibbert, Rush, etc.)?
