The Denver Broncos will be very deep at the tailback position come September as they have five solid backs competing for the starting position. Mike Anderson, Tatum Bell, Ron Dayne, Quentin Griffin and Maurice Clarett have all been heard from before, and all have the credentials to win the starting job. "We have five guys that have a legitimate chance at getting some playing time," coach Mike Shanahan said. "Right now, it's on a day-to-day basis. Sometimes, a guy will have a good practice and the next time, he'll have a decent practice. I've been impressed with all of them." At the moment, Anderson and Bell are the front runners for the starting position. "I've been real patient and just over the years, I've had some mishaps and some setbacks," Anderson said. "That's part of life. I'm still here and I'm out there now, and I'm happy." "Last year, I kind of waited for a chance to do something," Bell said. "I want to be in the mix right at the get-go this time."
