I still don't understand the logic pre-lockout that the Rangers overpaying Seager made Correa getting in excess of 10/325 inevitable.... it may have just said more about the Rangers (and their playing fast and loose with payroll) than it did about the shortstop market or other teams' desires to match that.
In order for Correa to get that kinda contract, there has to be another team out there willing to give him that.... maybe there still is, but as you suggest, there's a lot of signals that he may be back in Houston next year.
I wonder how much they know about Boyd's recovery from injury since non-tendering him or if there have been any discussions with him. With as thin as the starter market is getting, it may not be a terrible idea to bring him back if they feel Alexander can hold down the 5th starter slot and feel good about Boyd's trajectory.
