Cris Carter — BLASTS ADRIAN PETERSON … How DARE YOU Beat Your Child

NFL legend Cris Carter just WENT OFF on Adrian Peterson — scolding the Vikings running back for beating his 4-year-ancient kid … and admitting his own mother was incorrect for hitting him as a child.

The whole thing was incredibly emotional — with Carter appearing on ESPN’s “Sunday NFL Countdown” and ripped the thought that Peterson’s form of punishment was OK because that’s how AP was taught when he was a kid.

“My mom did the best job she could do … but there are thousands of things i have learned since then — that my mom was incorrect.”

“She did the best she could but she was incorrect about some of the stuff she taught me … and I promised my kids I won’t teach that mess to them.”

Carter then hails the Vikings — his former team — saying they did the right thing by deactivating AP.
