a LOT of sense.
Seager could very well force his way into a permanent, ongoing roster spot (or fabulous trade chip) without being a regular at a position. He's the kind of guy that would be invaluable as a super sub in the IF, an occasional DH against certain kinds of pitchers, ready on a moment's notice to step in at 2B, 3B, or even SS if necessary, in fact, I bet he could handle LF for a stretch if need be.
And he just might look so good that you have to consider whether it's best to get him 400 AB off the bench or hand him a job somewhere as a starter (or, as alluded to earlier, sell him off).
Seager might not become all that this year. But then again, he might.
