Teams pick and choose all the time and I'm not sure when would it be a bad time to have "too many options". I mean if Keyonte is putting up crazy numbers like Donovan's rookie year then sure, "Hood" can go. But it simply hasn't happened and you are talking like it has.
It didn't hurt Curry's career when he had to share the ball with Monta Ellis. It didn't hurt Luka when DSJ was mavs starting PG coming in and Mavs was able to quickly see the talent that they had and send DSJ packing. If you are talented enough and your team isn't completely ignorant, I don't see how that's a bad thing. I mean we the jazzfans can probably speak from our own experience first hand with this DedEx development project. And how Knicks spent so many years passing up opportunitues to acquire true stars just so they can prioritize the development of RJ Barrett. If Keyonte's good enough then it really doesn't matter who we bring in. It would only motivate him even more to be the best player he can be.
