If Tennessee teams are going to be competitive at Regionals, 2 things have got to happen: First they need to be trained at an early age to not even worry about winning or losing. They need confidence on the ball at an early age and that come from quality coaches that are more concerned with player development than results. Unfortunately we still have coaches that "coach to win" at the early age by focusing on more tactial training then technical. I'm not saying that winning is wrong at the early age, but the teams that are trying to "play soccer" by trying to work the ball around, trying moves, making good 1st touches and actually are trying to do something with the ball instead of just kicking it as hard as they can to the most athletic player on the team relying on that player to score a majority of their goals. These teams are inevitably going to lose more games then they'll win. But a few years later everything will flip-flop.
Seccondly, I think someone made the arugment that population, competition, parents letting the coaches coach, etc are the reasons the Texas teams are successful at Regionals. All this is true, but in the end its the population size and competition that make them great. They have their North Texas leagues that all the great teams play in coupled with the Premier League that they play in, the new National leauge, the Red Bull League, great tourneys in their own backyard. They play great teams game in, game out. As with anything, the key to success is consistency. The only reason the Oklahoma teams are successful is called geography. By being right above North Texas and so close to Dallas, they have access to playing great teams and great tourneys. If TN was located above Texas, we'd be a whole lot more competitive, guaranteed!
