Well, Rondo's conclusion about Hudson was based upon just one play, I believe (where he broke up a pass). I think it should take more than that for him to earn a roster spot.
I'm perfectly fine with seeing Pruitt go, though.
As for Powe, I think Doc would have preferred to have him back now, rather than waiting and hoping another team doesn't sign him in February. However, he's got to publicly support Danny's decisions.
