I like your tiers. I will argue Wheeler will be a top tier FA and get paid like one. I get the feeling Odorizzi will be a target for the Astros... They love pitchers who live in the top of the zone and if he goes there, they'll find another level to unlock with him. Rosario makes the most sense to trade but again, I don't think his trade value is very attractive. They would have to pony up a good value prospect along with him to get something decent in return. Finally, I would prefer not having any internal option, no matter how many, fighting for the #5 spot in the rotation. Go out and fill all 5 spots with veterans they think will help win.
