My biggest concern with the Caldwell system from day 1 has been economics. With NIL being what it is, I see the most successful model possible being this:
-- Spend most of your resources on a "Big 3". You need 3 game changers that are elite on both sides of the ball. Ideally, you want a main ballhandler/floor-general type, a stud 6-1 to 6-3 wing shooter/slasher, and a rim-protecting rebounding-machine that can score in the paint.
-- After locking in your Big 3, you get bargain role players to surround them. You need 2 corner-3 shooters, 1 defensive specialist wing, a solid backup PG, and 2 rebounding paint defenders. All need to be solid on defense, none need to be great at offense, as they will be playing off the Big 3.
-- You use your timeouts and natural game stoppages to play your Big 3 about 35 minutes per game or until you have enough of a lead to pull them.
If you had a $5M NIL pot, you can spend $1M annual on each of the Big 3. Then, you have $2M left for the supporting cast, and it might be smart to only give real NIL money to the ones you actually expect to play meaningful minutes.
In the Caldwell system, with the same $5M, you need 12 high-level players who can all shoot, all defend baseline to baseline, all rebound, all play positionless defense, all are ball handlers. These players exist, but they are in high demand. Market value might be $1M each. You are at a disadvantage because your NIL pot has to stretch much farther than a team using the Big 3 model.
I love the Caldwell style system. I just believe at the SEC level there are many structural disadvantages that will cause it to fail. Efficient, smart half-court basketball paired with intelligent fast break and secondary break features appears to be the future.
