Donovan McNabb's agent made blistering statements towards Redskins coach Mike Shanahan and his son on Thursday. Fletcher Smith took aim at the Shanahans for the way they have handled the benching of his client. "I believe there is tension between Donovan and Kyle that's rooted in the fact that Donovan has suggested modifications to Kyle's offense based on intricacies Donovan has learned in his NFL career," Smith wrote. "For example, Donovan has asked all year that the team run more screen passes to help manage the pass rush more effectively. Ironically, Kyle decided to employ Donovan's suggestions after he unceremoniously benched him on Sunday." McNabb listened to questions from reporters Thursday while sitting in his car after practice but did not answer before driving off. He was benched before last Sunday's game against Dallas and told by Mike Shanahan that he would not play the remainder of the season.
