^^^My thinking behind it is that the W's need size above all else right now. He would give you size, the mobility to keep up in that system and a legitimate post up player. You could slow it down from time to time and run the offense from the inside out and keep the D guessing.
@Chree you're right the "when healthy" is the big if, but if all you got to give up for him is Al Harrington I think its a gamble worth taking. you trade a guy who is not a big factor for a guy who could either not be a big factor or who COULD be a huge factor and a game changer for you.
