The logic, which certainly does exist with some managers, that closers are "paid for saves", it's akin to starting players just because they make more money. Which means Sandoval should be starting over Devers for the next two seasons.
However last year, Terry Francona introduced the idea of using the best reliever, Andrew Miller, when the game wad on the line, going so far as to occasionally give him the save over the closer Cody Allen. THIS is the smarter way to run the bullpen. And why we really need Francona back...
