I had a guy very similar to Mori. Drafted him as a SS but he only became a power hitting 3B, still won a few GGs. Same batting average. His VsR split was 10, but he had a decent career. Because he could play a position. I can't see filling out an entire lineup with guys like this, because you're going to have to figure out how to deploy so many 1B-caliber gloves. That Ferrer guy above, he's been shoehorned into RF.
Andy Hardy is a guy I just had play the back half of a season as an injury replacement on a team going nowhere. I was never fully decided on whether he'd even make the majors, as you see from three full seasons at AAA. If this thread stays up I'll update his progress next season, but I find it hard to believe he hasn't already overachieved in this first half season.
