Idiot. I am not saying a Curry / Morant quality player are transferring to UK or anywhere else, he would go to the league. My point was that just because a player is at a mid- major foes not mean he is legtovers or trash. But if players that good can come from a MM, then guys a step below can as well, guys who can perform as good or better than 50% of the 5* in coming FR.
With a transfer you know more what you are getting, so you have a higher floor than a 5* FR but also a lower ceiling.
Also some players are very good college players but not pro material, maybe because undersized or a step slow, and this under recruited.
And some players simply take longer to develop. The extreme example was a 6’7 low rated F that went to Navy, and 3 years later was a 7’0 AA and future Dream Team player.
