Imagine This:
During the 1999-2000 season (Pierce's second season, antoine's 4th) a team offers the celtics someone like Jerry Stackhouse, Rasheed Wallace, Antonio McDyess, or Gleen Robinson (i.e. a slightly older, more established player that is top 5 at his position, definitely not top three, a frequent all-star but not a starter, and a non-MVP candidate) for BOTH Walker and Pierce.
WOuld you consider that?
Tyreke has 3 years of 17+/5/5 and Demarcus is already a double-double average at 21 years old.
I would trade Rondo in a heartbeat for just Cousins and PG filler. I doubt Sac does that. No way they do a 17/5/5 guy and a 16/11 guy, both under 25, for one 14/10/5 guy that can't shoot.
