Not everyone with ties to the Cowboys organization has faith in young wide receiver Dez Bryant. Daryl "Moose" Johnston weighed in on the situation with some pessimism. "I don't know what you do with Dez Bryant because when Deion Sanders gives up on you that speaks volumes to me," Johnston said. "Deion goes out of his way to help young guys and try to help them reach their potential in the NFL. And when Deion says, 'I can't work with you anymore,' that's the first time he has ever done that. "This is a person with unique talent but with unique issues. And it would be a disappointment for Dez, number one, his family, the Cowboys, and their fans if he doesn't live up to the potential he flashed as a rookie . He was by far the most talented guy on that field many times during last fall. And the sky's the limit for that kid. And I just hope that at some point he understands and realizes that he shouldn't waste two or three years because his head is not in the game." While some have compared Bryant to one of Johnston's former teammate Michael Irvin, the ex-Cowboy warns they have positively nothing in common. "Don't ever to compare him to Michael Irvin because they are polar opposites," Johnston said. "Michael was high-profile and he had the 'Playmaker' nickname, but Michael was the hardest worker on that team. So, one of things you have to be careful with is that all of a sudden (because) he's high-profile and he's dynamic as a player you reach back and compare him to Michael. It couldn't be further from reality. "We had big personalities but we had guys who came to work and all they wanted to do was win football games. And hopefully that's what Dez realizes�that this is not about finishing your rookie contract."
