Packers safety Ha Ha Clinton-Dix is a rookie, and he still has many lessons to learn about how to survive in the NFL. He received an important bit of knowledge during Sunday's game against the Patriots, though: Unless you are, I don't know, J.J.

Clinton-Dix is the poor bastard wearing No. 21 in the video above. After watching Gronk shed two potential tacklers, Clinton-Dix thought it would be a good idea to try and lay a big hit on the freight-training tight end. Things didn't work out so well him! After the game, he came to regret his judgement error:

Clinton-Dix may not be feeling so hot today, but at least he didn't get himself thrown out of the club.
