It saves the defense 30-40 seconds. It’s a dumb rule and should be changed to give teams the option of running the clock or declining.
Luckily it didn’t hurt us but it definitely helped Miami.
Imagine if there was 2:30 left when Allen got the first and Miami had no timeouts. Game should be over. Instead the clock stops at 2:30, Bills have to run a play. Miami could get the ball back with 30 seconds or so all because of the rule.
