Is this too optimistic?
* On average, teams lose about 20 of 85 scholarship players each year when they've used up all eligibility. Thus, there's ~20 losses. (I didn't look up the actual number.)
* We have 29 players that have announced their intent to transfer.
* It's still early, thus one might assume another 20 players will enter the portal.
That leaves us with ~70 losses out of 85 scholarship players.
Then, on the bright side, we rebuild around those 15, plus 1-2 players who entered the portal but decide to stay, plus ~10 of our previously committed recruits who decide to stick with ISU, plus ~5 walk-ons who earn scholarships.
That gets us to 32, which means that the staff will need approximately 53 transfers and/or new HS commits.
Again, too optimistic?
