I like the South American idea, M2. Go there for a few years then a major European club.
I don't view it as an indictment of MLS. MLS is the best thing that ever happened to U.S. Soccer. It's just that MLS can only take you so far. Look at MLS like they're a double-A league in baseball. Before MLS, the only players who got a chance to play professionally were those who were either good enough to go straight to the majors and skip the minors (VERY rare) or showed enough innate ability that one of the major european teams would take the youngster into their youth development system (every major team has their own youth development teams and camps). MLS is the conduit that has allowed the players who couldn't make the jump directly the chance to play soccer as a profession and try to either stake out a spot on the National Team here in America or improve to the point where they can make that AA jump to the 'Big Leagues.'
Freddy is somewhat of a special case in that he is WAYYY ahead of the curve. He signed with MLS, I believe, when he was 14. Now he's 17. MLS has been good for Freddy in his young career, but it is near-time for him to take the next step. I love M2's novel approach of going to South America. His flair and creativity and ideas would only improve in such an environment. He could become the #10 that we have desperately needed. European tactical abilities with South American flair? That could be a potent combination when combined with Freddy's innate abilities and intelligence on the pitch.
