Thanks Jeff and Matt - great replies. This is something I’ve been meaning to ask for a while.

Jeff, makes perfect sense why this would be more prevalent on the baseball side than football.

Matt, I agree with you - there's probably enough out there to keep a collector like myself interested, but for the advanced football collector, they'd probably have to supplement type collecting in some way.... Personally, from my experience, one of the things I like about building a set is that I learn about the cards, variations, history of the players from that season, etc. - when I worked on HOF rookies, I didn't feel like I learned much because I'd grab a card or two from a set without much concern to its context and then move on.
