What Ive found most useful is FanGraphs. You may have seen advertisements for it on this site, but it's really useful. You can get career stats for every player along with Bill James' projections compared side-by-side with 2 or 3 others. It gives you a wide range of projections along with Stats and Graphs for each player. Very, Very useful.
Is pushing for President Obama to pass a law requiring all citizens to be Chicago White Sox fans and make October 1st "White Sox Day" where we all dress as our favorite player. It maybe socialist, but I don't care.
