This is the most important hire as you all have already pointed out. Unfortunately, this one worries me immensely. Pro style offense isn't going to work in C-USA. How many schools still run it at the G5 and successful with it? Boise - which is more of a modified multiple offense. You just have to be better at every single position for it to work and I don't think we're ever going to be able to recruit at a couple of levels higher than our conference mates consitently at every offensive position. College offenses moved to spread for a reason, because it creates mismatches all over the field if you know what you're doing. Pro style offenses don't really do that for you. Which is why most of the NFL has abandoned it too, because parity means you can't out leverage the defense like the bigger market teams used to be able to do.
There's a reason why one of his first commitments was a punter. Mason is going to put the best players on defense. Try to shorten the games. He's going to try to play a bunch of games at 17-13, 20-14, etc. I personally don't think that's going to fly in C-USA. Because even with a good defense, Liberty, Jax, wkcc are still going to often get their points and score in the 20s or even 30s even if we have the best defense. I also don't think it's going to excite the fan base.
I'm going to point you to one very useful example. Troy. Troy goes 11-2 and wins their second straight conference title. Even with the sixth ranked scoring defense in the nation, they still averaged 28 points per game on offense with over 400 yards of total offense. They could have been 12-1. One of their losses was just like the type of game I described that MAson wants. A 16-14 loss to JMU. One possession made all the difference in a win and loss. Two other games - even with a top 10 defense - they needed 27 and 31 points, respectively to beat Western Ky and Louisiana. Being able to score in the upper 20s and 30s even with a great defense is 100% necessary. It's the difference between a conference championship season and an 8-4/7-5 season.
