Walker was healthier last season than either Odorizzi/Paxton, but super fragile the seasons before that. Tough to say who is the more durable one going forward, but I mean, the team will have a lot more access to medicals etc than we do, so they'll make a more informed decision than I can
Odorizzi is probably my brain's choice, but I really do find Walker intriguing for reasons that aren't necessarily all that brain-thinkie.
