As Dan Shaughnessy observes this morning, the Pistons fans were taunting KG at the end of game 4 with a "Timberwolf for life" chant. Shaughnessy also observes that KG is the primary reason Boston is still playing. So while KG is a tremendously gifted talent, there is a larger legacy at stake.
In a way, the taunt was really a compliment to the Celtics heritage. Russell, Cowens, Havlicek, Bird, McHale, and Parish all earned their stripes. When the chips were down, they came through. Larry Bird took a pretty good team his rookie year and won 61 games. But he wouldn't have been Larry Bird without the three titles. Russell wouldn't have been Russell without the the 11 rings.
KG will be stuck with "greatest complementary player of all-time" label unless the Celtics bring home the hardware this June. It's still do-able, but as been often noted as of late, the Green appear to lack that killer instinct, or if they have it, lack the talelent, ability, or experience to act on it, which basically amounts to the same thing. They appear helpless to do anything but wait for a game 7 to make the situation do or die, again, because they can't or won't speed up the process.
As he has proven throughout the season, there are ways for KG to dominate that don't require him scoring 40 points and grabbing 20 rebounds, including 15 points and 10 rebounds in the fourth quarter. So I'm not sure it's the old "KG needs to step up and be Michael Jordan" debate. He simply needs to be the best player on the floor and ensure a W tonight, and keep doing so until number 17 is ours.
Otherwise, he won't escape his humble origins as a Timberwolf.
