Drawback to that is the defense has longer to look at the formation and mentally review the tape. I think there's definitely something to it. No mental breaks, as much as no physical ones.
Really, watch that team. They dusted defenses no matter what, but the most lethal was in the hurry up sets.
That's obviously situational and two-sided. There were times vs. UGA and Clemson they had to slow down and try to figure out what the defense was trying to do.
