Bill Belichick has been a part of the NFL since 1975, and obviously cares very deeply about both the league and the sport.
Belichick usually stays in his own lane when it comes to league matters, opting to work within whatever confines the league hands him and the other 31 teams. In league meetings, Belichick sometimes uses his clout and intellect to raise objections to new proposals and make owners think about all of the ramifications, but he rarely serves as a catalyst for change.
That has changed this year, with Belichick submitting four rules proposals that would alter the game. One of his proposals is quite radical and he is bringing voice to what he believes are four important issues overall.
