Troy Aikman believes that he could still play effectively in the NFL. "There's a lot of discussion about Brett Favre's arm strength," Aikman said on a Fox Sports conference call this week. "I can assure you that when Brett is 50, he'll have enough arm strength to play in the NFL. "It's the legs that start to go. Even for me, right now ? I work out a lot ? I'm approached [by people who say,] 'Wow, you look like you could still play.' Well, I could still play ... just as long as I didn't get hit."
