He's been playing 3B for 10 years in professional baseball (7 MLB + 3 minors) and played baseball at 3B, before joining the Sox system.'
Yes, he has shown signs he can play very well at 3B for some short and moderate stretches, but he has never put that "ability to be a GG 3Bman" for nearly a long enough stretch to even come close to one vote for GG. I don't see it happening.
No, 3B defense is not our biggest issue, but defense is pretty big, overall, and our 1B D sucked, last year, too.
If Devers could play plus D at 1B, quickly, we could gain on D at 2 positions, at once, in theory.
It would, however, force Yoshida to play LF, and he is probably worse than Duran/Refsnyder, unless we can trade Yoshida and improve at 3 positions with the moves.
