It's a no brainer, the guy would be coming in on a cheap contract, you do it everytime. It's not going to be one and done with Hill, they'll be looking for another arm.
I don't see the Birds going after him personally, but if they did land him, I'd be both shocked and happy the Jays are going after players of his stature, and help to our team as a whole.
Edit: Like floored!
