I've seen it vary from 46-50 in various auctions houses. I just picked up a Cardinals Issued James jersey and the size is 46. I think he wore 50 with the Colts for the most part. I imagine that the diference in jersey style might account for the size difference.

I know that Larry Fitzgerald wears a 46 Cardinals jersey and he weighs about the same as James so it would make sense. I just figured I'd check with other collectors who might have Edgerrin James gamers.

Thanks guys
