Hey guys, I'm having a rigorous debate between a friend and I about who was a better player, Albert Pujols or Mark McGwire;  Now, I clearly know the answer is Pujols, but I can't seem to find any statistics to back up my claim; I tried searching on Google with no good results, and I did use fan graphs as a source, but my friend insists it's irrelevant because the two haven't played in an equal length of time;  anyway, without actually starting another discussion on the issue which I'm sure has been beaten to death over and over again(or has it?) can anyone link me or guide me to a good discussion on the topic or if there are any good stats to back up my claim.  I know I've read some commentary on the relative subject here but can't find it anywhere!   Any help would be great! Thanks!
