Yeah, RT being a starter seems like a real long shot. If he stays a reliever though, the Jays have built up a decent pool of potential high end lefty relievers, especially if Little has turned a corner.
Flu is solid if unspectacular.
Little if he's figured control out has shown flashes of dominance.
Tiedemann has the kind of high end stuff that could be high leverage.
Coleman is now in AAA, getting knocked around a bit early on but there is time to figure it out.
