I think Steph should stay with the team because
1.His contract is expiring (Trade value during season)
2. Contract year (he will be a 20 and 8 guy once again)
3.There isnt another point guard available that has half the talent that he has.
As said he really should stay i mean it is a win win situation if he does well we take it if not we just sit him and just let his contract expire.
