The transfer is all money orientaited. Like you say why would you moved to a not very strong league if it wasn't for the quarter of a billion dollars you were going to be paid.
This won't be the first of the Europeans moving to the US though Edgar Davids is poised for a transfer to FC Dallas. Davids is a Dutch midfielder in his twilight years, and hasn't been able to hack it in the Premier league for the last two years, he obviously wants to come to the US for one last pay day.

During the 1990's the English league saw an insurgence if foreign players especially to the Premiership, at the time people predicted the end of Britsih football as these foreign players were entering the league well past their prime and obviously just wanted the money. For a couple of years this was the case, but we now get good young foreign players plying their trade, and this makes the Premier League the best league in the world for football.
The same could now happen in the US. The money is obviously there, what they need to do now is market it properly. Sky Sports pay big money for football, the pay millions to show Premier League, Championship, League One, League Two and the Conference from England. They also show German Bundesliga and Spains La Liga so another countries football would fit in nicely, especially as next season they are not allowed to hold a monopoly on the TV games and some have to be distributed on other channels (Setanta and terrestrial TV).
Personally I can see the US league going from strength to strength as long as they change a few things. The first being salary caps, as you can't attract the best players in the world if they can't be paid millions and the structure of the league is changed as I think it is currently crap. Eastern and Western conferences may work in other sports but football you need a proper full league with aprox 20 teams in it, playing each once home and once away in a season. Whoever is top of the league is champions, no play-off crap. Introduce a domestic cup competition and then try and introduce a proper World Club Championship, maybe to take over from the current European Champions league or run side by side with it. You get temas like Manchester United, Chelsea, AC Milan, Real Madrid, Bracelona and Bayern Munich playing over there, sponsors money will coming pouring in by the bucket load, and I am talking billions of US dollars.
The potential is there, the money is there, it just needs marketing and structuring correctly.
