Have never been a fan of these X to make Y roster compositions beyond isolated positions and only after loading up in other areas.
The problem is that more times than not, you don't have your best matchup on the field because your "player" isn't "a player".
Despite having Lind/Lee hit something like 34 home runs and 107 RBIs, they felt nothing like having a proper 1B standing up there because they were constantly out of position in terms of matchups.
In the end, it just adds more volatility into the equation, making it more difficult to get a consistent product out.
