What's there to be worried about? That McGowan gets hurt again? If it happens. It happens. The team should go with the best arm in that role and not make its decision based on fears of injury. The Jays can't control whether or not he gets hurt.
But they can control the role he occupies. With Janssen, Santos, Delabar, Cecil and Loup in the bullpen having an arm like McGowan out there is overkill.
I'd rather see McGowan in the rotation over a journeyman like Redmond or a just-a-guy like Rogers.
This is kinda how I feel too. At this point so what it McGowan gets hurt? As a team, we've got a ton of reliever depth.
If his body holds up as a starter, its a huge coup, because we know what kind of stuff he has.
Don't get me wrong, I like the guy, I don't want to see him get injured, God knows he's worked hard for it. But it seems like he's interested in starting too and thats what he wants. I feel far more comfortable knowing we've got a guy with top of the rotation stuff, but injury concerns rather than playing it safe, putting a guy with borderline stuff but knowing he can make 30 starts.
There's also nothing wrong with keeping a strict pitch count on him. Even if he only gives you 5 very good to excellent innings each start, you can throw in Redmond who was very good in his first time through the rotation last year. If he can give you 2-3 innings every 5th day we're fine.
