Vargas was the best up and comming fighter I have ever seen. He was pushed fast and achieved a lot but if he was more "carefully" managed he would have had a longer career and maybe have been more successful but nothing is guaranteed. Some fighters need to be pushed quickly because they will self destruct if they are not kept busy ala Tyson, others would get bored and be unmotivated if they had no challenge which may have been the case for Vargas.
