Not really, maybe Smoak can't play any other position well other than 1B; I just threw the question out there.
PS: It is good that Blue Jay fans have come to expect good defense. It was only a year ago that Jose Reyes was throwing balls away at SS, and a couple of years ago they had Juan Francisco play some games at 3B, who had the fielding range of a pylon.
The Blue Jays have become an enjoyable team to watch on defense, it wasn't that way a couple of years ago. So no, Smoak shouldn't play at 3B, especially since the Blue Jays have Barney to back up Donaldson. However, is Smoak slower than Saunders in LF - I am not suggesting him as a permanent replacement, just a fill in if required.
Please no insults - I am just asking what would happen if Smoak was in LF? Would he have no range, he has a good accurate arm and a good glove. I have seen Smoak run into the foul territory to catch popups, so he does have some fielding range.
