I'd say go after a player that you like that has already retired. I'm also a Braves fan, and I had a Heyward jersey, then he got traded, Kimbrel jersey, he got traded. So, I grabbed a Chipper and Dale Murphy jerseys. I don't collect any new players exclusively, but if I pull a cool card, I'll keep it.
Super Collecting Mark Rypien and Juan Gonzalez
