From what I've read, there's 350 rookies per year, not 1466. There were like 21,000 rookies for the entire game spread over 60 classes. Basically, there's 4 groups of 15 classes each. That's an interesting point that pluto brought up regarding CPU preseason cuts. I know that the creators suggested that there will be players invited to each camp that weren't available in the draft, so that's a possible source of players. Josh also mentioned players from other leagues (Canada, Arena, etc) that may jump on a squad, but that's supposed to be quite rare. I would think that the draft, the post draft free agent bidding, the "non-roster invitees" (baseball style, I suppose) and the other league entrants will make up all the camps. I can't imagine they went into as much detail as they did and didn't make enough players. I'm assuming the four sources I listed will cover all the teams.
