A deal between the Cowboys and Titans that would send cornerback Pacman Jones to Dallas has hit a major snag, according to ESPN.com's Ed Werder. Dallas is refusing to give Tennessee a fourth-round pick in this month's draft and another selection in 2009, and there have been disagreements over money as well. "It's pretty muddled," a Dallas source told ESPN. "Any time you have disputes over both the picks and the money, you have a real problem."
