i am curious what you mean by "skirted the line"? a quick google search shows that for the 2021 classification, enrollment numbers for the largest 4 AA schools are as follows: CPA - 448, LA - 453, Webb - 494, Chatt Christian - 525. doesn't look like LA is even close to skirting a line. it looks like they are exactly where they are supposed to be. FWIW, BA is the smallest AAA with 461, so LA would be the smallest AAA school if they moved up. I do think they could move up and play with those schools as could CPA.
in any case i'm proud of the season Lipscomb put together.
