The NL has to be the stronger league at this point... The NL MVP candidates (Berkamn, Utley, Chipper Jones) and Cy Young Candidate (Webb) are Far Superior to those of the AL currently... I think the ASG this year will be really cool, hopefully the AL surprises me.
Webb being 9 1 means nothing since hes pitching to much weaker lineups. It is not even close. The NL has MAYBE 2 teams that would content in any AL division. Dbacks and Cubs. MAYBE!!!!
So what is the time frame were talking here. You say overall...does that mean from the beginnings of baseball? Then the answer is NL. Are we talking in the 2000's? The AL. Are we talking this season? Then it might be a bit of a debate.
