Fangraphs has Assad with one last option next year, though these things are complicated enough they're not always right until we get closer
And yeah fair point that all 6 of those guys making it to April healthy and rostered is far from a guarantee. I guess mainly with how many question marks are going to be there on the big league staff and the injury experience this year I assume Jed's going to go for max-depth. Two long relievers on the big league team, Assad on paper at Iowa, probably a Vince Velasquez type signing or two, etc.
No lie this bit is starting to get weird
