1. He's a perfectly fine outfielder
2. You don't just give up talent like that
3. It's more important to keep him than have a better bench
4. But he'd be in Buffalo if he had options
5. The Jays bench isn't that bad - most teams don't have great MLB caliber players on the bench anyway!!
(These are all things Mike Wilner told me on the Jays talk when I called to ask why Sierra is on the team)
I thought he was going to be acceptable too. Well, like 2 dWAR and -1 oWAR or something like that. But he's way worse than that. Time to move on. He's depth now, nothing more.
