Okay, so to go over some metrics to see how well Liberty would fit in the "new" American, I took a look at the 2019 football attendance and the 2019-2020 men's basketball attendance, both the most recent on the NCAA file.

Here's how Liberty stacks:
East Carolina: 33,134 / 3,931
Memphis: 38,816 / 16,312
Navy: 31,970 / N/A
SMU: 23,633 / 4,395
South Florida: 31,823 / 3,754
Temple: 29,460 / 6,425
Tulane: 20,271 / 1,743
Tulsa: 18,741 / 4,043
Wichita State: N/A / 10,315
Average: 28,481 football / 6,365 basketball
Liberty: 18,272 / 4,476
LU would have the worst football attendance. An increase of over 10,000 would be needed to just meet the average. That looks impossible within the next couple of years. On the other hand, basketball may be approximately 2,000 less than the average, LU would have been fourth in the AAC as Memphis and Wichita State are outliers that really move the average up.
If we want to be an AAC (or whatever conference), we can't count on the new conference to pull us up and reach our potential. We should be at least hitting the averages before we are invited, not expecting the new conference members to boost our attendance when we start playing them.
