a fine line

I'm not gonna lie, I like a man that's confident. : ) How a guy carries himself can reveal a lot about him and how he might treat me. I am a girl, I overanalyze things on a daily basis and tend to judge quickly and be impatient, it's in my genetic make up. Getting back on subject here, confidence reveals character about a guy. It shows that they can handle themselves in situations and that they feel good about themselves. I like a guy that stands out in the crowd and does so without being a jerk, a guy who is comfortable in his own shoes and being himself in front of anyone and everyone.
But,
There is a fine line between confidence and arrogance. Cocky guys are a no no. Confidence is sort of like cockiness, but with class. Arrogance is just plain stupid. Arrogant guys are simply striving for attention and are a bit shallow in my opinion. They are annoying and inconsiderate, not to mention self centered. Perhaps I'm hitting a bit below the belt on this one but I would say I'm speaking for the majority of the ladies out there :P
The reason this is all coming out is we played a boys soccer team today, a U-14 club boys soccer team, I believe. Though they beat us, and they were, for the most part, taller than us, each boy definately had a bigger head than our entire team (note: we combined jv and varsity) put together. Their sweeper sat in the back and talked about how he could dribble the ball up the entire field past every single one of our players, take a shot, and score. I wanted to deck him. The odds were probably in his favor but still, did he honestly find it necessary to say it out loud? Not only that but you would also think that he would realize that he would be attending high school this upcoming year, meaning that the underclassmen he just played with saw that he was a cocky _____ and as you know, girls can't keep secrets.
I suppose I just don't understand why boys think girls find cocky attractive. I've already admitted confident is an excellent find, but over the top confidence is a major turn off. I like a guy to be smoooooth, not a jackass.
