I agree, though there is still two months of the season to be played and injuries do happen. Having depth in the bullpen is important as well. A lot of posters now are forgetting the months of April and May when the Jays were losing guys to the IL and had no depth behind him. Everyone on here was complaining they wanted a stronger bench and better arms etc. Funny how things change since the Jays just swept the Red Sox and the entire lineup is healthy now, most posters think everything is perfect and the 25-man roster will be healthy all the way through October. Doesn't work that way.
All I said was Jason Grilli is an example of a BP arm who struggled before the Jays acquired him and he turned out to be the most dominant Jays reliever down the stretch. I'm not saying Trevino will be that guy, could be someone else, though I have no problem adding Trevino or someone else with some upside as a 3rd bullpen piece if he's available for cheap.
