The thing about the Hall of Fame is that there are no levels of distinction. The guys there are just the best in the history of the game. Pujols and ARod should both end up in Cooperstown, and people can debate about who was the better player. Yes, Pujols is the superior hitter, but the game includes more than that. ARod could run like the wind, steal tons of bases, play great SS covering lots of ground with a canon arm. I'd probably pick ARod to start a team, but maybe my metrics for base running and fielding etc. are a little different from WAR. No single stat is definitive in determining who is the better player. It may be the best measure out there, but it is not definitive.
