If it's $10M difference, there's just no way it stays together. UA & CU will bolt - at least.
HOWEVER
if that $22M per still is legit even if 2 teams leave and are backfilled by SDSt and SMU... then you could get the 8 remainers up to $25M by giving the 2 newcomers a half-share.
If you take that another step to 4 teams leave, and add 4 replacements who get half shares -- then the remaining 6 could get almost $30M each. Its probably a stretch to keep the same $22M per team, but MAYBE just UW/UO are worth that much for their games, idk.
