The NFL came out with a few proposed rule changes last week, and Matt Forte is not happy. The Bears running back either first heard about the possible NFL guidelines on Sunday or just couldn't hold his tongue anymore, as he tweeted some strong words in opposition of one particular rule. In hopes of increasing safety around the league, one such proposal includes a runner avoiding leading with the crown of his helmet to absorb/initiate contact when carrying the ball. "The proposed rule change for running backs might be the most absurd suggestion of a rule change I've ever heard of," Forte tweeted Sunday. "In order to lower ur [sic] shoulder u obviously have to lower ur head. It's a way of protecting ur self from a tackler and a way to break tackles." "U can't change the instinctive nature of running the football." Owners will vote on the proposed rule changes at the NFL Annual Meeting, which started Sunday.
