Yes, but did you actually bother simming a season without names, or auto names which has no effect. You will see a drastic difference. Option QB's are over 1000 yards rushing without real names. Denard Robinson went for over 800 on 140 carries without names. Turn the names on, the option QB's disappear from the top of the list and Denard loses over 300 yards of rushing, and is sacked more often. Don't do a single sim with him named and assume "Oh, that looks normal; it's fine." Compare it to the original roster and I guarantee you'll see differences. Variance is possible, but if you do it a few times, there will be obvious differences in the balanced Robinson vs. the scrambling Robinson. On your named roster, go take a look at Andrew Luck as well. Bet he has more YPC and number of carries than he ever should have.
