Donaldson checks in at 14
The reigning AL MVP is making a run at a second straight trophy — remarkably putting up an even better year than he did a season ago — and has established himself as one of baseball’s premier all-around players. In terms of short-term value, few players would improve a team today more than Donaldson, which is why the Blue Jays won’t give him up; he’s the reason they’re contenders. But as a 30-year-old with just two years left before he hits free agency — and that 2018 salary could break arbitration records — Donaldson doesn’t offer much in the way of long-term value, and while he’s going to be making a fraction of his market value, he won’t exactly be cheap. But given his high level of current performance, the Blue Jays would get far more for him than they gave up to get him, even after using up half of the controllable years they acquired; the Donaldson deal may very well go down as the best trade in Blue Jays history.
