actually, i think quite a few of the South American players will be missing AO quallies, so probably money is a big factor
also, they don't have many tournaments to play in SA. Sao Paulo yes, but then no futures, and then Bucaramanga, Salinas.
I guess yes, we need more quantity in Challengers here in South America for sure, but more than that, we need them to be more organized, like in a pack.
* Previous to AO there is no Challenger that helps, but there should be more Futures (guys who play future wont try AO obviously) besides Mexico, there are not Futs until end of Feb.
* Previous to LA clay swing...only Bucaramanga, that's ridiculous.
* Before European clay swing where latin american guys should have better chances, last year there were a few in brazil and Colombia. But, in my opinion, this is the time where it should be more packed (around March and April) during the year. Good results may imply big boosts or at least enough to play ATP 250/500 clay tourneys in Europe.
* For instance, by the end of the year there was an interesting quantity of tourneys in LA. Great, but they would've been way more helpful if some were scheduled before May.
