It's going to be like the One and Done era. Once in a while you'll see an all-new team make a run, but you really have to mix kids that have been in the program with transfers.
You'll need to develop a core of high school kids you develop and mix in some transfers. Seems the best transfers are guys that have multiple years left and can mesh with the rest of the team. The key is convincing your high school recruits to stick it out when they aren't playing as freshman.
One thing to watch for, especially in Basketball but also football. Power 5 teams using smaller schools to place kids that won't play as freshman but will play at the smaller school. The Power 5 team will cover NIL, and the lesser school will get a year of that player in exchange for protecting him from other schools. Basically, a Farm System.
