Went absolutely nuts in season 22 of Gleeman2. Toledo is - at best - neutral to power hitters. Didn't have a high patience rating, but got it done.

Played in a better hitters park, had better contact than Byrd, and more patience. He did have a decent season 26, and has been - in general - productive. But certainly not a world beater.
I think these guys in many ways are kind of a crap shoot. They can produce eye popping numbers one season, and be somewhat mediocre in the next. As long as they don't kill you in the field, and you have openings at 1B, DH, or LF, they can be a cheap source of production.
Just my take in what I have seen so far with the supper high power guys who aren't stars...
