It was decided on the field. That was a late hit. That’s been a late hit for years. Do not hit a guy that is out of bounds. Period. That’s the rule. The defender broke the rule. That all happened on the field. The penalty was legit, and necessary. There’s isn’t any judgment on that. Mahomes was out of bounds. No judgment. And got hit. No judgment. That has been an automatic penalty for years.
Looked like a judgement call to me. I didn’t care about either team but those last 4 flags made it the worst game in FB history.
