It’s so weird that they wouldn’t rubber stamp Bellicheat for the hall of fame. He was only responsible for:
Spygate (2007): The Patriots were caught filming New York Jets coaches' signals from an unauthorized location. Belichick was fined $500,000, and the team was fined $250,000 and lost a first-round draft pick. It was revealed they had filmed signals of various teams for seven seasons.
Stealing Play Sheets (Prior to 2015): Former employees alleged that a Patriots staffer would steal the visiting team's scripted offensive plays from their locker room at Gillette Stadium during pregame warmups.
Radio Interference (2000s): The Patriots were accused of frequently jamming opponent coach-to-quarterback radio lines, causing them to go out on key plays.
Bengals Videotaping Incident (2019): A Patriots videographer was caught filming the Cincinnati Bengals' sideline, which Belichick claimed was for a behind-the-scenes feature on a scout and not related to coaching.
Deflategate (2014-2015): While the focus of this scandal was on player involvement with under-inflated footballs, it remains associated with the team's reputation for bending rules under Belichick's tenure.
Illegal Substitutions 2015 (at the NFL owners' meetings), the league passed a rule change making it illegal for a player with an eligible number (who reports as ineligible) to line up outside the tackle box. Such a player must now align closer to the center (within the tackle box, like a traditional lineman). Violating this results in a 5-yard penalty for illegal substitution.
This directly addressed the Patriots' tactic, ensuring ineligible-declared players couldn't masquerade in wide/skill positions to confuse defenses. The rule was proposed partly in response to the Patriots' playoff success with it and aimed to promote clearer, fairer substitutions without overly restricting creative play-calling.
