The nfl needs to realize this is going to happen again. Here is the new rule. “If any Coach or team seeks to subvert any well established rule, they will be sanctioned, fined, and repeated offenses terminated.” This will go a long way to prevent Danny boy or others from doing this. This is not an nfl first because bellichick tried to steal calls and deflate balls and should have been terminated.
NO. Just enforce the rules - which the referees did. End of story. No need for rule changes. The existing rules worked just fine. Ignore the temper tantrums of the talking heads, and also the Lions and their fans. Dallas won the game straight up. The Lions tired to deceive. It didn't work. The proper foul was called (even if talking head and fans don't understand that), and the resullt was a penalty. The Lions had a choice at that point to try to kick the PAT to go into overtime. Instead they attempted two more times to get a 2-point conversion. Bottom line, is they had three opportunities to kick an extra point to go into overtime.
1st try - a 2-point conversion failed due to a foul on the Lions - properly called and enforced by the referees.
2nd try - a 2-point conversion failed, but a penalty on the Cowboys - properly called and enforced by the referees - negated the play, resulting in
3rd try - a 2-point conversion failed due to poor execution by the Lions and good defense by the Cowboys.
Result: Cowboys won the game. No asterisk needed. They are now the 2nd seed in the NFC, and can maintain that position with a win on Sunday against the expansion team Commanders, who have the 2nd worst record in the NFL.
Unnecessary overreaction: Rule changes preventing coaches from trying to deceive their opponents. Deception is part of the game. The Referees prevented deception outside of the rules by enforcing existing rules. Therefore, what is needed is for referees to continue to properly enforce the rules, as they did in the Lions/Cowboys game. No rule changes are necessary.
