The Indianapolis Colts have stubbornly stuck with the struggling Trent Richardson. The running back is listed as questionable to play Sunday versus the Arizona Cardinals with a calf injury, but the team expects him to be dressed. Offensive Coordinator Pep Hamilton said Friday, barring a setback, Richardson will start and lead the rushing attack. "We don't plan on changing our rotation with our backs," said Hamilton, per the team's official website. "We've always been a running-back-by-committee bunch, so we're going to continue to do that." This is where Colts fans shake their heads. Donald Brown has been the better back since the Colts sent a first-round draft pick to the Cleveland Browns to obtain T-Rich.
