It's pretty obvious what traits a cox must adopt and tries to learn to do a good job in this most unique position in the athletic world. I'll pass on the leadership stuff, napoleon complex garbage, and point out a secondary characteristic or two that coxes unintentionally inherit after riding in the box for a while. They can't drive a car anymore. They take 10 miles to change a lane,oversteer, can't find the brakes, and yell to the car a lot. This has nothing to do with the coxes' former driving ability.
Coxes also begin to squint a lot, no loss in vision, they just squint.
Strokes are born and made to be the most competitive person in the boat by far, and if they stroke long enough, become overly competitive in everything they pursue,or don't pursue. Don't expect to finish a game of Monopoly, Risk, or Golf with a stroke. The seat is the Bitch Niche. The longer one rows at seven, the more sophisticated and complex the bitching becomes, changing from a crude verbal rowing suggestion to the six man in the early stages to long winded level- voiced reasoned treatises after every piece explaining why the crew is slower now than last week. I was a team captain, looked up to leader of my college crew, kept my mouth shut and did my job.
