$1,000,000 from Kevin Durant. Very nice.
Kind of on the other end, Matt Kemp, originally from Midwest City, OK, is donating $1000 per home run he hits....until the All-Star Break. So far he's hit.......2 this year. (Kemp signed an 8 year contract extension in 2011 for.......$160,000,000). Quite possibly he is doing a lot of other charitable things (like giving away his jersey to a cancer patient). But if you are gonna put your name out there.......you gotta do better than that. If only from a PR standpoint.
As one Tweeter person put it "Kevin Durant is donating $500K for each home run Matt Kemp has hit this season." - Duk @KevinKaduk
