This is HUGE! I think this was the best move for Freddy, and here is why.
1) If he signed with a European club, he would play with the U-19s for years. He wouldn't see the senior squad for years. In MLS, he will start. He will go up against professionals, against guys who have played in the World Cup. MLS is stronger than the U-19s in England.
2) This increases Freddy Adu's chances of playing in the 2006 World Cup. If he signed with Man United, he would never see the field at Old Trafford. Now, he will be playing professional ball at 14. By 2006, he will already have 2 full years of MLS experience.
3) MLS and soccer in America in general will benefit a lot from this. Having a 14 year old professional will attract people to the sport. People will gain interest in soccer. Also, since Freddy signed a 6 year deal, there is a good chance that a European club will spend a lot of money on a transfer fee, which will help MLS financially.
4) Freddy will now be closer to home. His mom lives in Maryland. He won't be in a place he isn't familiar with.
Overall, I just think this is great. I am happy that Freddy chose to sign with the MLS.
