I agree about your meanings of Gastao Elias. It was the first time that I was able to saw him and I didn`t know that much of his performances in the past except that he was a player to watch some years ago but without big results as many players on the tour.
As you well said I agree with you that he should spend sometime on the Futures tour and then make the jump to the challenger tour. Tennis is so competitive on these days that players with a big talent keep struggling with themselves and are not able to make the jump to the Challenger tour. Unfortunately Elias is one of those cases as he has the tennis to play the Challenger tour.
He's been attacked in this last years by injuries, and that's not very helpful eihter. His carrer high (before the injuries) was well enough to enter some Challengers MD's, when he was like 16 or 17 years old. But now he have to know that he has to start from zero, once again. He need's a good coach. I don't know who's the coach, now, but surelly not the best for him, IMO. Sometimes you've got to make one step back, in order to make 2 steps further, in the future...
