I can't find links anywhere that this is in fact a rumor. The only thing I DO know and DID hear was on ESPN a few days ago about if the Celtics were to trade any of the Big 3 where would they go and Minnesota was a team that came up.
It wasn't based on any knowledge beyond the fact that they knew Wesley Johnson had been under performing and with the drafting of Derrick Williams you know Beasley is most likely the odd man out. So with that knowledge they said maybe, maybe but probably not.
I, personally, am not sure what I think of Wes Johnson. He has been not performing well and could be a bust... or could be that Minnesota was using him wrong... after all it is Minnesota and Rambis was not a good coach. I wouldn't want Wes, Beasley or Ridnour though honestly. Minnesota would have to throw in a 1st round pick in order to take on those headaches/busts.
