First, understand that OOTP isn't really created to exactly replicate real life. It's bread and butter is fictional league play. Always has been. It is best to leave pre-conceived notions of players at the door when you're playing OOTP. Nobody is going to be exactly like they are in real life.
Second, you can always edit these players yourself. Or go to the
Mod forum or check out
Padres Fan's place.
Wimberly, a career minor leaguer, isn't going to be high on the roster makers' priority list to get right. Same with
Eric Young.
OOTP is incredibly customizable. If you don't like something, you can usually change it yourself.
