BBM issues the same Rookie Edition set every year. I'm not really sure what there is to say about this set, other than it's out. That's not such a bad thing, I guess - it's predictable and serves a purpose. And with everything BBM did right last year, I'll let that slide.
The base set clocks in at 126 cards; 12 of those are Early Days. There are a few parallels: 86 of the player cards have silver versions (100 copies each), first draft pick players also have gold parallels (30 copies each) and a red signature version limited to 17 copies each.
I don't have any of the hits yet, but retired players (up to 90 copies each) and prospects (up to 60) both have autographs in the set, as well as a First Draft Pick autograph set limited to 30 copies each.
Finally, BBM issued a 12-card promo set with a PR prefix. It's also possible that there are additional promotional sets which don't appear on the BBM checklist, such as bookstore promos. These are usually identified by different coloring, card numbering, and a notation on the card.
