I have noticed through all my years of soccer that club ball can end up giving you more exposure to colleges. I played on both a very good club team and a very good high school team... always some of, if not nearly always, the best in the state. If I were to compare my biggest tournaments or games between high school and club soccer, there were undoubtably more looks during these bigger fall tournaments than any highschool events I played.
As far as developing, most of the higher tier players in the state also play on some club team during the fall. You can't hardly reach a higher level of abilitiy unless you have that training. Join a club team, go to some harder camps, keep playing. That's all it is; it's tough work but it pays off.
About ODP, I'm not so hot on that subject because i feel that TN ODP is lacking in many areas. I do not feel that they bring in the best players in the state from past experience. However, it does have its benefits when it's on paper...
