Was KG every a game time decision during his injury in 09?
He was every bit a gametime decision as Ray is. For most of the games, he was ruled out the day before, or the day of the game, just like Ray has been.

Get your facts straight
The Garnett injury WAS NOT a gametime decision on most games
APRIL 18th
Boston Celtics star Kevin Garnett, the centerpiece of Boston's 2008 championship and a key to its hopes of a repeat, could miss the playoffs because of a knee injury that has limited him to four games over the final two months of the season.
Celtics coach Doc Rivers said Thursday that Garnett will not be ready for Game 1 against the Chicago Bulls and possibly won't be back at all.
"It's not official that he's out for the entire playoffs, but it's official as far as I'm concerned," Rivers said before practice at the team's workout facility.
