"If running backs can be compared to royalty, then Marion Barber was moved to a ceremonial position on Sunday.Jason Garrett refused to anoint Felix Jones as the king of Dallas Cowboys running backs, but the most casual observer could have 20-200 vision and still see the obvious: Jones is the most capable running back on the team.After the Cowboys lost a 34-27 decision to the Tennessee Titans on Sunday, however, Jones did not stay around to celebrate his first regular-season 100-yard game."I'm not really focused on what I did," Jones said as he hurried toward an elevator. "I'm not really ready to talk about what I did. If I can say something about my team, we're going to get it together."If the Cowboys can turn around their 1-3 start, they will likely help their cause by getting the ball to Jones as much as they did on Sunday.Jones carried 15 times for 109 yards, which included bursts of 34 and 20 yards and led the Cowboys to their best rushing performance of the season with 141 yards.Barber had only six carries for 19 yards and after the first series of downs, Jones was getting carries on first and second down instead of Barber.But Garrett, the Cowboys offensive coordinator, was still maintaining a position of neutrality."Marion started the game and Felix got more opportunities as the game went on," Garrett said. "So we like both guys. Both guys are going to play for us."Garrett has steadily maintained that position, but even Cowboys owner Jerry Jones said during the week that Garrett was simply being "coy."There seems to be little doubt that Barber lacks the explosiveness or power that he once had. He has 42 carries for 144 yards this season, an average of 3.4 yards per carry.Jones has passed Barber as the team's leading rusher with 197 yards on 37 carries for an average of 5.3 yards per carry."
