MIAMI (CBSMiami) – The Miami Dolphins appear to have settled on Lamar Miller as the team’s starting running back heading into Week 1 of the regular season.

Miller was long expected to be named the starter based mainly on his speed and elusiveness, but he didn’t run away with the job during training camp.

At different points in the preseason, Daniel Thomas appeared to be edging closer to Miller with his play. Miller’s first game will see him match up with a Cleveland Browns defense that was not very good against the run last year.

The Browns defense ranked 19th in the league in rush defense, giving up 118.6 yards per game and better than 4 yards per rushing attempt. The Browns also gave up 14 rushing touchdowns in 2012.

When Miller has to run between the tackles, he’s going to run into a mountain of men from the Browns in the form of Ahtyba Rubin and Phil Taylor. Rubin is 6’2” and weighs 321 pounds while Taylor is 6’3” and tips the scales at 334 pounds.

Still, even though Miller topped the depth chart, head coach Joe Philbin left the door open to changing the depth chart this week.

“We still have a full week of preparation,” Philbin said. “Today is Monday we’re not playing a game for six days, and we’ll see how things go.”
