The 3 Minute clock in H2H is so stupid in my opinion.
It feels like cheating when you defer the ball, because even if they score on their opening possession, you have 3-4 minutes to chew the clock down to halftime.
Then, in the second half, the game is (at least) tied up and you have the ball, and if you get a touchdown on your drive it's pretty much a win.
What makes this even better is if you have a reliable way to convert 2-point conversions. Then, you can get up by 1 at halftime and make it a 9-point (2 score) game if you get w TD after the half.
