I'd sell Wiewegh , but if you feel you need a little bit more inside shot, sell Vlaovic instead. None of these guys are gonna excel at high level D4 though, so you're gonna need to sell them eventually.
I think Branly was an OK deal for you. Gives you a okay level point guard for this year and next, and especially because you're a D5 team, buying this guy will help you short term. 36,000 isn't a significant amount, and it will not hurt you in the future.
