Here is a simple answer. If a coach has overseas connections who have proven trustworthy in the past (i.e. they don't hype a player who is not good enough to play for that coach), then basically no effort is expended by the coach to recruit that player. However, there is still a downside. No one is perfect on talent evaluation. DVDs don't tell the whole story. Even an overseas contact who does not over-hype will make a mistake once in a while. When that happens, the coach will be frustrated that he took someone else's word for it too much. (Believe me, these coaches do not really see the players play all that much. They cannot go overseas for many recruiting trips at most schools, and if they do, it is hard to judge how good player A is when he plays against player B when you don't know either player.) ITF rankings are notoriously unreliable indicators for a variety of reasons.
So, there is some advantage to seeing players in person within the U.S.A., where you have an idea what TRN ratings mean, you have an idea how good the opponent is, etc. When it gets harder to do this, the alternative just got more competitive as an alternative.
Very short answer: When plan A (recruiting trips to domestic tourneys) gets harder, and plan B (make offers to foreign recruits) stays the same, the existing balance has changed somewhat in favor of plan B. There is a balance of foreign vs. domestic right now, and nothing got worse about the foreign option due to USTA actions. How much change in the balance? Who knows.
I was speaking to a college coach who is a friend of mine, and who I can be straight forward with.
He is a coach of a mid level D1, ok academics, ok location.
His team is about 1/3 Americans and 2/3 Foreigners.
When I asked him why the team couldn't be more American ( private btw),
he countered with the fact that he is doing a better job than a lot of other coaches who are recruiting all foreign.
Yes, he deflected the question.
His thoughts on a coach in his position who recruited all foreign were that they were "lazy".
That it just involved emails with recruiters abroad, and no contact with parents.
He thought he was doing a better job as he travelled to some of the big national tournaments and would watch the matches
which he thought was more important than TRN rankings as the ranking never showed if you went deep into a national tournament, which is why he said coaches still looked at USTA rankings.
Now, he didn't know about the cuts to the tournaments in 2014, and when I told him that all was left was two during the summer with 128 draw, he said that hurt him as he wasn't looking for the best American kids as they weren't interested in his school
( academics and so-so location, location hurt more than academics he thought).
So, I think the 2014 changes will turn the tide to more foreigners,
and really dislike that Lew Brenner is saying college coaches have to be creative, when it sounds like some coaches are lazy.
Besides, seeing a state high school championship, most of the smaller schools don't have budgets to fly around our country.
