Agreed. If (big “if”) the Sox do decide to re-arrange the infield to accommodate Campbell, a better alignment is Devers at 1b, Campbell at 2b, Story at 3b and Mayer at SS. Maybe not the best alignment, but better than Campbell at 3b. (Casas to DH or trade? I have my doubts.)
Campbell’s lack of a position might position him as trade fodder as well.
