In case you missed it, Bostic of the Bears was fined $21K for a hit on a receiver. A legal, clean hit that was text-book perfect (no flag thrown). At this point in the NFL; I have lost the ability to understand what a "defenseless WR" would be, seeing as Willie catches the ball, turns, and has taken at least 2-3 steps before being hit. Apparently there is never a time you can tackle a player with the ball.
Total embarrassment for the NFL to fine a guy for this hit and it's this type of sh** that's going to cost a team a game when a ref throws a flag in a critical moment. Disgusting.
