With all the hexagonal information out now, and all of the speculation and analysis about home and away advantages/disadvantages, I'm curious about what exactly is our home advantage? I'm not being fatuous here, because we obviously have an outstanding home record, but everyone knows why México has a home field advantage -- altitude, smog, enormous, defeaningly loud stadium. Everyone knows about the home field advantages of the Central American teams -- stifling heat and humidity, rabid fans and subpar field conditions. What is our homefield advantage? I mean, we have passionate fans, but we don't have that many of them, and I don't think Sam's Army really makes anyone nervous like some other fanbases, especially when they are mitigated by usually strong away team support in the stadium. Sometimes we have cold weather, but really, other than the February Mexico game, I don't remember that many instances where it was anything other than pleasantly cool. At the end of the day, our home games are usually very pleasant atmospheres for playing soccer -- nice fields and stadiums, nice cities with nice hotels, decent weather, pretty respectful fans (if not outright partisan away fans). Sounds like the perfect away game situation. So what is our homefield advantage? Why do we do so well here? Obviously, it is much more comfortable to play in the US than to go down to Saprissa or Azteca, and you would expect to have a better record in a neutral or mildly positive site than in a majorly difficult one, but we have been too disproportionately dominant at home (to the point where other teams fear needing to get points in the US) that a better answer is necessary. Why are we so hard to beat on US soil?
