I would keep Santana. If you're all in on a rebuild ( shhhh, the rebuild has already started ) then you need a veteran presence to help guide the younger players. Ervin is already filling that role for the pitchers. I think Dozier is filling that role for position players. Aren't there 2 other veteran pitchers coming back next year? Hughes and somebody I can't think of now. If there are 3 veterans on the pitching staff, I'm OK with that. Room for Berrios and Duffy (or someone else). The offense is doing OK. More walks, better OPS, OBP and fewer K's would make the offense pretty special.
