Though in the end you might be right that everyone else gets tendered, I don't think that means that these decisions were already made. It could just mean that Plouffe was the only obvious one, so they made it right away to give him a head start in FA, and to have his 40 man spot available for Rule V protections. Santiago- they could have wanted more time to see what the interest in Ervin looks like. And also to see what the FA market looks like in terms of years and $. Bullpen guys- might have wanted more time to see what the prices look like, and to evaluate internal options. Escobar is probably an obvious tender, as is Gibson. Edit: Also, and I could be wrong, but I think with players who are a consideration to come back at a cheaper price, it makes more sense to non tender as opposed to releasing. I'm not sure any of these guys fit that possibility though, perhaps Santiago.
