The football roster numbers are somewhat inflated due to the extra year of eligibility granted due to the 2020 Covid season. Trine has several 5th year seniors who elected to play another year, which makes the senior class larger compared to what the typical senior class would look like. I'm sure it's that way at many D3 schools. Trine always pulls in a hefty freshman class in football, but that number drops significantly once they become sophomores as many guys realize they will probably never see the field and elect to concentrate on academics, or perhaps transfer to another school. And I agree about why you would come to a school as a freshman QB knowing that your class includes numerous other freshman QB's? I would seriously consider looking at other schools. This season Trine's QB elected to take his Covid option to come back for a 5th year, and it will be his 4th year as a starter. So it hasn't been great for other QB's on the roster at Trine to see action on the field, other than mop up duty on occasion.
Trine's enrollment at the Angola campus, by my guess, is closer to 2200-2300, of which over 40% are in the school of engineering. I can never find a breakdown when Trine publishes their total enrollment, which in 2022 was 8400, as that enrollment number includes their satellite campuses in Fort Wayne, Detroit and Phoenix, plus those enrolled in TrineOnline. Trine University is by no means 'desperate to stay in business'.
