Mostly because we don't tend to be an efficient scoring team. Teams that rely on defense to win close games are going to be hurt.
Efficiency margin. Both offensive and defensive efficiency. If uncapped, there's actually a tendency for those metrics to overrate good defensive teams that play a slow pace. When Virginia beats Maine 46-26, that's equivalent to an 84-47 win.
They've removed the separate 10-point MOV, but efficiency margin already counted MOV, so it's just no longer double counting.
I'm most interested in the verbiage surrounding SOS. The release says "strength of schedule is based on rating every game on a team's schedule for how hard it would be for an NCAA tournament-caliber team to win" which sounds an awful lot like Wins Above Bubble. That would represent a significant improvement in the methodology and would do a much better job of valuing each individual win and loss.
Unfortunately, they're also sticking with the Q1/Q2/Q3/Q4 system. That particular system will always favor the big schools that have an easier time racking up Q1 games on their schedule.
