The NFL year is over, and so much happened.
We got Jon Gruden's return to the Oakland Raiders, where he just went and traded everyone (not literally). We saw Kansas City Chiefs QB Patrick Mahomes take over the league with sidearm, underarm, right-handed and even left-handed passes.
Heck, we even saw the Cleveland Browns win a game.
But how much of this year do you remember?
