Kenpom has it at 125, 128, 176, 178 fwiw. Manning’s two teams at Tulsa were 131 and 51. And yes talent matters on the defensive end too
Those are pretty horrible as well for a power 5 team.
Do you know how the differences are calculated? I was pretty shocked when I saw the numbers on that site. I expected something more along the lines of the Ken Pom numbers.
Either way, there is a systemic problem. Depending on which numbers you use, the defense is either about what you would expect for a Sun Belt team or horrific for a Sun Belt team.
