The top is a slippery place.
It does not matter if it were the U.S. Open tennis championships or your dorm Halo crew. We (and I focus again on post-adolescent males) make so much of a deal on being on top of everything from physical strength to button-mashing that all other purposes of life are lost in the instant where winning and losing is on the line. If I were to go back to biology again, I might blunder an attempt to explain why it is easy to be fired up and adjust to be first when you are the second best, whether it be in the state or on your floor. However, one thing remains constant - if you are at the top you can fall pretty hard, since you have no motivation.
So for those standing on top - beware, people are grasping at your ankles. For those underneath them, good luck catching up. A competitive game needs two players, not one.
