The Lakers aren't giving up Gasol for Pierce. It will never happen. No chance. Now if it was Pierce and Scola for Gasol, I could certainly see them making that trade.
I really think the Lakers are thinking a salary dump type trade. Something like Pierce for Blake, Walton, Barnes, Ebanks, Dallas 1st. In a separate trade I then move JO to them for the Odom trade exception since players would have to be cut anyway.
Saves the C's money short and long term, gets a first and a look at Ebanks, and get a decent sized trade exception.
