If Ulis shows consistency on his floater and proves he can finish amongst the trees, he's gone after this season. More power to him if he goes.
If he comes back, I could still see Cal go out and convince Fox to play alongside him. It would be intriguing to watch a Ulis/Fox/Monk trio, or a Fox/Monk/Alkins trio.
Even in the unlikely scenario where all three of Alkins/Gabriel/Bridges go elsewhere, I feel confident about next season provided we land Monk and Fox. Those two are the key to '16-17. Anything else is the cherry on top.
