I'd take him in a second, even though I can't stand him for dogging it so badly. If he had played even close to his ability during the regular season, that game 7 would have been in Boston, and it might well have made the difference in the series.
That said, if we platoon the C spot, dividing up the 48 minutes evenly between Steims, JO and Sheed at 16 each, and have them go like heck during their short spurts, conditioning shouldn't be too much of an issue and the benefits of having a legit C (instead of Wilcox or KG at 5) WOULD improve the team quite a bit.
It could be the difference.
