I really like MFN, I've watched every game I've played and I love the tinkering.
One thing that bugs me, however, is that my team will sometimes just run it 3 times after the 2 minute warning at the end of 2nd half, seemingly no matter the score, just to run down the clock.
Sometimes, all I want is for my team to look like they want to win. I've even seen my offense run the same play three times in a row, yet it took around 2 minutes to do so. Come on guys, we're trying to achieve something here!
