Unrealistic to think that professional athletes will finish career and then transition to active duty - at most they will do minimal training and PR work. Also, grads going to medical school incur additional service obligation - not a freebee for them.
Assuming that with lowering the impediment to a pro career academy athletes would have similar draft results as Stanford/Michigan in football 2019 - 5 (not Alabama with 10) and UVA in baseball 2018 - 6 (not Kentucky with 13):
11 draft picks in one year and didn't even get to basketball, hockey, soccer, golf, tennis, undrafted free agents, walk-ons, or any women's sports. Better to have a D-3 caliber athlete going directly to active duty.
