There are clear Biblical statements prohibiting such intentions of the heart. Jesus said if you want to become great be a servant and he may have said something about not punching people in the face. There is also an element of good biblical competition; Paul said he runs the race to win the prize. Paul also talks about training and not beating your fists at nothing.
So I am competitive, did I mention that? But something I get excited about is confrontation with someone huge, mammoth, nay even gargantuan. I recognize that I will likely loose, but there is a feeling of redemption in merely rising to the challenge. I wonder if that's how King David felt? "Man this Giant is about to crush me but I'm going to try and plunge one of these rocks into his skull as he's running toward me, and if I die everyone will think I'm awesome." I would think that.
So one of the pressures is to be the best or leave the game, let's say that's an inappropriate pressure but the other pressure is good; I want to do the best I can and try to kill this thing, I probably can't but I'll take a crazy, consistent, aggressive swing and hope that God backs me up.
