It's been really great to see that KG is playing so well. Definitely has a lot to do with the team playing well, too.
I do wonder how long it can last, though. I think it's normal that a player like KG, at that age, will have stretches where he looks great, and then stretches where he looks cooked (he's looked both at times this season). I also can't help but wonder if, as some have guessed, his extra intensity and determination to produce is a sign that he knows this is his last season.
