Ok, due to Doc River's recent announcement, I'm bumping my thread up.
KG can still play for 18 mins. I know that Doc doesn't want the Kevin McHale story to happen to KG, but to be frank, he'll be fine during the offseason, after a small arthroscopic procedure to remove the calcium deposits. It's not fractured... McHale's foot was broken in '87.
Now, given the way the schedule looks, KG can take the first two series off, playing a few garbage minutes, here and there, to keep himself, in mental game shape for the Cavs series.
