Note to NFL receivers: If you’re running across the middle, and Zach Brown is looming, yes, he will try to take your head off. The Washington Redskins linebacker left no doubt as to where he stands in the NFL’s ongoing player safety debate Monday when he proclaimed you shouldn’t play football if “(you) don’t wanna get hit or hurt.” Brown, taking the defensive player point of view, started with this tweet. It was an apparent response to Green Bay Packers wide receiver Davante Adams, who was concussed by a dirty hit from Carolina Panthers linebacker Thomas Davis on Sunday in the Panthers’ eventual win. It was the second time this season Adams has suffered a concussion from a dirty hit. Chicago Bears linebacker Danny Trevathan missed a game for his head shot on Adams earlier this season.
