The SOM cards are designed for the season which they were produced. The cards are normalized to that season. So of you play with just the 82 card set they player do (within reason) play to theire cards.
The problem here is the are lifted our of their season and put into some mystery bizzaro world where most team have good hitting and good pitching. At least better than a team would have in real life. Also in the Myster card format teams tend to get better over the course of the season because bad cards are dropped and replaced with better.
The game is about winning. I don't know who said it, but someone said "stats are for losers". If your winning and your RS is better than RA then your team is good.
It is fun to see guys put up numbers, but I'd rather put up wins
