"Whether he settles into a rotation spot, a swingman role, or a multi-inning relief job"
I'm excited for Klein and I think he'll do well, but no, no and no. This team needs late inning relievers and they are exponentially more valuable than long-men, swingmen and back-end starters.
The team infamously gutted the team last year, but that was mostly by trading away Duran, Jax and Varland. I simply cannot comprehend how this organization is dragging it's feet in trying to make pitchers like Klein ANTHING OTHER than the next Duran, Jax and Varland. He absolutely, positively will not be more valuable as a #5 starter or low leverage, inning eating reliever.
