Stats give you the ability to quantify things and compare every possible variable for an informed decision.
Yeah, really. Baseball is still full of people who use sentimental evaluation criteria like leadership, hustle, or even physical appearance as part of their evaluation of a player.
Wouldn't you rather make a decision on a player based on data you can put your finger on rather than a hunch or something that's not able to be rendered mathematically?
I'll just refer you to what asindc posted in reply to you. I also fail to see how you can connect the Pujols signing and Hawk or anyone else's opinion of modern baseball metrics.
