There will always be a couple of dudes who don't get as much time as they think they deserve (Catchings, Crawford) and a guy who showed flashes of being good and will take money somewhere else to have a bigger role (Boskovich, Baker could be an example of this). We might also lose a major contributor every offseason because they are our 4-5th priority to retain and someone else's number 1 priority to go out and get. If you also consider that we are actively bringing in other players, there will be times when a current player feels threatened by an incoming player (Hall, Keita) and chooses to leave or is shown the door.
Not predicting anything. Don't know anything. Let's remember though, that if a player enters the portal he can come back. There's really no reason not to enter, see the options and then get more money for coming back if you choose to.
The great news is that we have a ton of momentum, KY has built a super strong reputation already, it is a known fact that BYU is aggressive with NIL, so I'm sure we will have our pick of the litter with guys who are in the portal.
