Were these players created automatically by the game? If so, then I doubt that there will be anything outrageous about their ratings. Just let the GMs in question change the positions of the players to SP or MR and watch what happens.
I've converted a few position players to pitchers and vice versa in on-line leagues. They never really panned out for me, but I've seen it work for another GM or two. Their development is just the luck of the draw, same as with any player.
