This is a great concept. I have been part of a Team Collectors group (Tramers and Therion are part of it) that is going on for 10 years now. We have had folks come and go, but still have a core of 10-12 collectors that are still active. I would be happy to help send some players/teams if I have them. If they are on a team that someone collects in my group, I wouldn't have much.
For me, I am a Kevin Youkilis player collector and a Red Sox team collector.
