A (likely) no to all 3 and it gets rough.
It's a likely no to all 3 imo. White is 28 yrs old with 22 career MLB starts and pretty rough looking numbers as a starter. Kikuchi always had some glaring red flags in his analytic profile, and Shatkins signed him anyway. A bounce back for him would be to a bad, HR prone #5.
Pearson is dead at this point. If he becomes a useful arm out of the pen, that's a win. He's not a starter prospect anymore and probably hasn't been for 2 yrs. Pure hopium to think otherwise. There's a better chance that Tiedemann breaks through and takes the job mid season, than Pearson coming back from the dead to claim it in camp.
Fwiw, hope for Juenger or Palmer to steal the job in the spring. At least there's some hope in the younger arms.
