The read

On rating alone Tulane Green Wave are 6.3 points better (#56 vs #97 of 240), and TULN add 3.1 for home field. The clearest mismatch is the passing game: TULN passing ranks #27, USA defends it at #112; the other way USA #78 into TULN's #74. The model lands on TULN by 9.4, essentially the market's number — no spread lean. On the total the model sees 45.9 against 55.5.
