In other words you'd have done the same thing Kirk did. As for why did he stay? Maybe against many beliefs he did want to stay once upon a time.
Yep, never said that I blamed him for doing it because that's exactly what you do until that sure thing is in the bag. I suspect that he'll sign the tag again if it's offered and run full stop to whichever team offers the best contract (the aforementioned $30 outside). I too believed that Kirk wanted to stay once upon a time, but unlike too many here, that changed for me, and likely him, as I suggested, after the failed post 2015 contract negotiations. I also don't blame folks for holding onto hope that the deal would get done after that, they want their front offices to do the right thing, unfortunately, we don't have the luxury of employing hope with Mutt and Jeff in charge.
