Overrated and Underrated Stats

People don't realize the importance of some some stats, and people put to much emphasis on other stats, Here I take a look at those stats.

Overrated:

Pitch Count: Why do people always worry so much about the number of pitches someone throws? The only question should be: are they still effective? When the answer to that is no, then you can take a pitcher out of the game.

Batting Average: People say a walk is as good as hit. Then why should we care how someone gets on base?

Underrated:

WHIP: Maybe instead of pitch count we should worry about this. WHIP: The number of walks and hits per innings pitched a pitcher allows, or effectiveness. 

OBP: A stat that makes walks as good as hits.
