The read

On rating alone USC Trojans are 15.8 points better (#20 vs #126 of 240), and USC add 3.1 for home field; USC carry a rest edge worth 0.2. The clearest mismatch is the passing game: USC passing ranks #4, UL defends it at #81; the other way UL #114 into USC's #41. The model lands on USC by 19.0 against a market USC by 28.5, so the spread lean is UL by 9.5 points — a lean, not an edge: against closing lines this model covers about 49%. On the total the model sees 54.7 against 63.5.
