The read

On rating alone Wake Forest Demon Deacons are 8.7 points better (#46 vs #122 of 240), and PUR add 3.1 for home field; WAKE carry a rest edge worth 0.2. The clearest mismatch is the passing game: WAKE passing ranks #68, PUR defends it at #123; the other way PUR #116 into WAKE's #12. The model lands on WAKE by 5.8 against a market WAKE by 3.5, so the spread lean is WAKE by 2.3 points — a lean, not an edge: against closing lines this model covers about 49%. On the total the model sees 54.0 against 49.5.
