There is no doubt that its the catcher. Here's an analogy for you. The

catcher makes the calls behind the plate and serves as the "director"

of the entire production. The pitcher serves as the "actor", but

without the director behind the scenes making all of the crucial calls

-- the production fails. And often times, like movies, the catcher

still fails at making all of the calls. He is involved in each and

every pitch. Meanwhile, an outfielder or first or second baseman doesn't come

close to being that involved and integral towards the outcome of the

game.

I would say pitching is by far the hardest position. Although I agree with you on many points you made about catchers, I still think pitching requires the most discipline and technique.  I would argue that it would be much harder to teach a catcher to be a decent pitcher than for a pitcher to become a decent catcher. There is just something special about pitchers that not everyone has. 

Every position is difficult and deserves a great deal of respect, but my vote goes with the pitchers. 

I just read these words that a St. Louis Cardinal fan wrote into Yahoo Sports columnist Jeff Passan--who voted shortstop as the most difficult position:

"Do you really think that shortstop is the most demanding position? Seriously? Have you ever sat behind the plate and caught a game? Not only do catchers have to call a game, direct the infield and keep baserunners honest, they have to do it in a crouch, all game. Catchers have to remember scouting reports, work with the pitching staff, keep themselves as healthy as possible and, oh, yeah, try to make time for batting practice."

At a game the other day I was very focused on the catcher since it was a friend of mine's daughter. It made me realize how tough that position is.  She's also one of the better batters on the team also, which makes her efforts that much harder.  My vote is for the catcher!
