there's a thread on the main board about this:

I'd like to see AA ratings for defense/speed/steals/etc for EXCEPTIONALLY rare cases. OOTP should generate a player like this once every 10-20 years (for each respective rating, perhaps each respective position). The example they use, Ozzie Smith, is the perfect reason to have such a thing. A guy like that wins the Gold Glove almost every year...because they're legendary at defense.
Having a AA speed/steals rating could also give you that player that can make a run at Rickey Henderson-type SB numbers. This separates a guy like Henderson from, say, Johnny Damon. Damon is certainly a gifted base stealer, and one of the best in the leauge *currently*...but he's not even on the radar of a Rickey Henderson.
And maybe, just maybe, you get a starting pitcher that ends up with a AA endurance rating this is ALSO a brilliant talent...and you end up with someone who goes out and throws 20+ CG every year.
The best thing about this being random is that a guy could end up being a AA shortstop...but have crap ability at hitting. You get a guy that is AA at something AND is also good enough to make the roster anyway...you've got something special.
The more I think about this...the better the idea sounds.
