Seems really far fetched to me, its well acknowledged that Larrier isn't getting a sniff for draft - but 'scouts' and the next level understand his game and look at him differently? Um, him not getting drafted means scouts look at him and elect to go in a different direction. It doesn't even seem there's a chance Larrier gets a G-league look, especially as that league gets more serious. Most decent high D1 players can play pro ball overseas, but that seems to be consensus only option for Larrier.
Yet given all that you say early in the thread; "... coming back is absolutely the worst thing he can do." ?! Hyperbole sure, but I don't understand. If Larrier can turn it around via basketball in Czechoslavakia there is surely some upside to working hard and improving within the NBA radar screen at UConn. Might be a bad fit for both, but if so, that says more negative than positive about Larrier and his pro aspirations.
