My general philosophy for baseball card collecting is that there are 2 types of players: Long Term & Short Term. Long term players would be those who consistently put up solid stats from a young age, making it very possible that they will have HOFer career stats (i.e. 500+ HR, 3000+ Hits, 300+ Wins, etc…). Short term players would be those who either put up good to great stats for a few years, or don't start having strong numbers till mid career (or start their MLB career later), making it difficult for them to have HOFer career stats. Personally, I collect long term players, and buy & sell short term players. Of course, other factors to consider are personal contributions to their teams, reputation, team performance, etc. One of my all time favorite players to collect is Andruw Jones. I've been buying his cards since before he became the youngest player to hit 2 HR's in a World Series game back in '96 (breaking Mantle's record). If he stays healthy and plays to a normal retirement age, I think he can hit 500+ HRs & 3000+ hits. In my opinion, it wouldn't hurt to have a Jones 95 Bowman/Bowman's Best RC or two in your collection!
