He can play the 3, and Pierce can play some 2, so he could work as the primary wing backup (a big slow, but also has size advantages). Bring back Marquis and you have a nice 2/3 rotation.
Don't see it happening, but Marion's a world better than most of our options. Unfortunately, the contract goes as long as Pierce's.
Don't see Dallas doing it unless we maybe included Perk or Baby. I don't like either idea that much; however, if one went, Marion could play some backup 4 and really isn't much more undersized than Baby.
Don't see it happening though. Can't see Cuban dumping salary without getting something immediate in return.
