It seems to me that the Jays didn't have a lot of interest in signing anybody for more than a year or two other than early target Gausman. Understandably the club intended to give Roark one final opportunity to prove that he wasn't totally cooked. Atkins mentioned wanting to provide opportunity to young rotation candidates, with guys like Pearson, Manoah, Hatch and Woods Richardson all at or rapidly approaching MLB ready status it's not hard to see why the front office didn't want to tie up too many rotation spots. With the rash of injuries and poor performance it's definitely easy to second guess not signing anybody else for the rotation, but in the end the bullpen ended up being the bigger concern despite really being beefed up in the offseason.
