I'm not sure if I'm just an optimist, but I see Fiala become a steady 50-60pt player for us. I don't want us to trade him.
I'm leaning towards an idea that if extended Stone or any other player with term is not an option (for whatever reason), I'd rather not make a trade. I agree, with the inconsistencies this season, I'd rather push to fix those inconsistencies than throw in an additional piece to mess it any further.
Give the team more time to work and find out who fits and who doesn't. If it all goes south in playoffs, you have a better idea what needs to be done in terms of personnel change. I'm talking about both coaching staff and players.
