Can two bigger DTs aid Indy's run defense?

Posted by ESPN.com's Paul Kuharsky
LaJuan Ramsey and Daniel Muir have yet to appear in a game for the Colts this season. They may not play Sunday in Houston. But to hear Tony Dungy tell it, the Colts two biggest defensive tackles can help a run defense that's been really bad.

Muir was claimed off waivers from Green Bay on Aug. 31. He played in three games for the Packers last season. The Colts signed Ramsey on Sept. 11. He was a Philadelphia sixth-round choice out of USC in 2006. He played in 15 games in two seasons with the Eagles and spent some time this summer with San Francisco.

"When you make moves like this, you hope that you find guys that are fitting in to what you do," Dungy said. "We have a lot of guys who wouldn't necessarily fit other places quite as well. You're hoping that what they bring to the table helps in your situation."

According to Dungy, the bye week was big for Muir (6-foot-2, 312 pounds) and Ramsey (6-foot-3, 300 pounds), the only Colts linemen who top 288 pounds.

"They'll be better for us, Dungy said. "This bye week was important for them, to be able to just strip away all the looking at another team and what type of offense we're playing and really just focus in on their learning curve of what we do. It was a good week for them. They made a lot of strides, and I think both of them are going to be able to help us."
