If Shaq's willing to play for the vet minimum (barring a sign and trade) and willing to come off the bench, I think this would be a great move: Perk will be out about half the season, and will likely take awhile to get back to form once he returns, and KG and JO have recent injury histories, so Boston could really use another solid big, and there are none available who are better than Shaq, who rebounds well, takes up lots of space, gets some easy buckets, plays solid D.
