The ranks for Tennessee Tech passing wise were uhhhh not great at the FCS level last year:
102/122 in scoring
116/122 in pass efficiency
98/122 in total offense
89/122 in passing offense
Wild they couldn't even pull from a top-half FCS team?
He was not the OC at Tennessee Tech and he was there 1 year as the HC was fired after going 20-43 and 11-29 in conference over his tenure. Before UConn hired him, he was named as OC for Southern Utah. He was OC at North Greenville, so let's look at those stats:
2019: Ranked 132/166 in total offense at 300.7 yards per game with 17 TDs.
2020: COVID
2021: Ranked 90/163 in total offense at 352.5 yards per game with 35 TDs.
2022: Ranked 40/163 in total offense at 401.2 yards per game with 34 TDs.
His passing offense in 2022 ranked 27/163 at 253.7 yards per game and 7.34 yard per attempt. To compare, UConn passing offense ranked 102/130 last year at 190.3 yards per game and 5.99 yards per attempt.
So, his offenses showed improvement each year and his passing offense was pretty good his last year although North Greenville was not a good team when he was there. The biggest plus for him is that he has worked with Sammis before so they should work well together.
