It is a totally random set. The cards have these kinds of variants:
College/Pros Same Player
College Different Players
Pros Different Players (same pro team)
Pros/Pros Same Player (different pro teams)
I would love to put the college uni patches together, but the serial numbering is weird too. Some of the patches are /50 or so, while others are /1. Same with the autos. Somebody on ebay has a patch auto partial set for sale. Really badass.
Also, there is a sweet Peyton Manning on ebay now with a Citrus Bowl patch.
