Everybody's favorite McClain writes here:

"The Texans have hired Long-time NFL defensive line coach Bill Kollar to replace Jethro Franklin, who was fired after the season.

Kollar, 56, has been Buffalo's defensive line coach the last three years. He also has coached the defensive line at St. Louis (2001-05) and Atlanta (1990-00). Kollar coached in Super Bowls with the Falcons (1998) and Rams (2001).

During his 19 seasons as a defensive line coach, Kollar has worked for head coaches Jerry Glanville, June Jones, Dan Reeves, Mike Martz and Dick Jauron.

Here's a copy and paste from the Bills website:
