Run defense improved?

[Joe Joe]

Last year, I thought the strongside of the defense was pretty porous last year, especially earlier in the year. Granted, Diles had a couple of good games. The weakside tended to be pretty strong due a lot to Mario.

This offseason, the Texans add two players to the front seven on the strongside in Cushing and Smith. The Texans gave up a 122 ypg and 4.5 per carry.

Is Cushing and Smith enough to get the Texans to being a top ten run defense team (4.0 ypc or less and 100 ypg or less)?
