As for the Promise to Payne, I have to believe its from the Pacers unless the Kings are out of there minds. No other lottery teams are really in need of a PG. I guess the Nuggets would be the third option if they plan to move lawson.
Payne getting a promise is just silly. Teams should not make promises and players should not bank on them. Too many things can change draft day, not the least of which is trades. As for who might have given such a promise, I don't think it is necessarily a team that appears to need a PG. Some one could have a trade lined up, someone may simply view Payne as the BPA.
As for Dekker, I don't think the Celtics should need to work him out to form an opinion of his ability. I am sure there were scouts at some Badger games and everyone watched him in the tourney. Workouts for such a known quantity as Dekker are not as important as they are for some other players. For example players from Europe, players like the big Indian guy who never played in college, or for a player from a small school who put up big numbers against lesser competition. These are the type of guys you need to see live against other top talent.
I am not that interested in Dekker or Payne and I hope the Celtics aren't either.
