The Dallas Cowboys have concerns about signing Dez Bryant to a long-term contract with guaranteed money due to his off-field issues.

"This is a genuine concern," Rapoport said. "The Cowboys, I am told by multiple sources involved in the situation, do not trust Dez Bryant off the field. They feared -- and they have feared for a while -- that it will all blow up in his face, that a variety of small incidents will all come back to haunt him. ...

"I went to the DeSoto (Texas) City Police Department. I found six instances of police coming to Dez Bryant's house -- that's where he lives, in DeSoto. Among the incidents -- and none of these were convictions -- there was a harassment incident, there was a robbery at his house, the fire department had to come and unlock his car that had a sleeping baby inside. All of these things give the Cowboys cause for concern. He's had anger management; they have a manager with him at all times. But they are very nervous, and this is one reason they have not wanted to give him the guaranteed money that most elite receivers get."

Bryant will be a free agent this offseason and has been one of the NFL's most productive wide receivers.

"Well, Dez Bryant just changed agents, so talks may start off," Rapoport said. "This was their best offer to Dez Bryant: 10 years, $114 million. Sounds pretty good. Well, I am told only $20 million of that was guaranteed, only $5 million signing bonus, and over the first six years, he would make $10 million (per year) -- not the salary of an elite receiver."
