On further review of Gibson's stat line, that 1.4 blocks in 28 minutes per game is actually pretty decent. If it weren't for his age (29), he might make a good pairing with Zeller for interior defensive purposes. I just can't justify moving young guys like Sullinger (22) for a player that old while we are in a rebuilding mode. A guy like John Henson (23), if he is available, is more like what I would have in mind.
