Most football followers don't take the trouble to get all the inside information that it takes to get a true picture of what someone like Dez is actually all about. He once had many sceptics, even among a considerable segment of Cowboys fans until they came to become far more intimately familiar with his inner workings.
Dez has had more than his share of hardship growing into the person and teammate he is at present. He's now proven himself as one of the most devoted and capable players on the team in addition to maturing into a respectable adult. People who aren't really familiar with someone and have simply heard a few negative things are often quick to judge.
I do believe most of those who have come to know Dez more closely have come to respect him both as a player and a human being as well. We humans are extremely complex creatures. Observers who form judgments based on only a few known facts seldom afford anyone like Dez a fair shot. Granted, he's still a work in progress but I'm confident he'll be just fine now and most likely, well into the future.
