Kevin Durant Is NOT Pleased With Peyton Manning!

Oh, it's ON!  We've got ourselves a brand, new, sports feud for the ages!  Watch as Peyton Manning fires the first shot on Kevin Durant!  BAM!  

Manning was hosting the ESPY's (ESPN's annual awards show) last night, when he joked about Durant; who controversially left the already-good Oklahoma City Thunder for the even-better Golden State Warriors, and won an NBA Championship as a result of it.

Watch the diss below!  And someone call Vince McMahon...I smell a cage match!
