Tom Brady and Bill Belichick may have had their differences in the years leading up to the eventual separation of the famous quarterback-coach duo. But they are still part of the old guard; the “get off my lawn” mentality, if you will.

Brady went after the NFL for expanding jersey eligibility, saying the new rule and new numbers could “make for a lot of bad football.” Belichick apparently feels similarly.

Mike Florio of Pro Football Talk reported the New England Patriots head coach “hates” the new rule:

“Per a source with knowledge of the situation, the Patriots were one of a handful of teams to vote against the rule that dramatically expands the available jersey numbers to linebackers, defensive backs, running backs, receivers, and tight ends,” Florio wrote. “Coach Bill Belichick, per the source, hates the new rule.”

Just save it, Bill.

Florio did not give Belichick's stated reason for being so opposed to the new rule, but it is probably fair to assume he feels similarly to Brady in terms of the rule potentially creating confusion.

This disgruntled attitude comes from two of the biggest film heads in the history of professional football. Shouldn't the likes of Tom Brady and Bill Belichick have a very clear knowledge of opposing personnel and schemes through film study? Their grievances just seem rather confusing.

Peter King of NBC Sports had previously reported Kansas City Chiefs would not have proposed the rule had head coach Andy Reid believed it posed as some kind of deterrent to offenses around the league.

If the architect behind one of the most high-powered offenses in the game isn't opposed, why are Brady and Belichick so upset?
