Michigan State promotes Dan Roushar

Michigan State has promoted offensive line coach Dan Roushar to offensive coordinator.

Roushar replaces Don Treadwell, who left the team to become head coach at Miami (Ohio).

Roushar has coached the Spartans' offensive line for the past four seasons and served on Mark Dantonio's staff since 2005. He served as offensive coordinator at four schools: Illinois (2004), Northern Illinois (1998-2002), Ball State (1994) and Butler (1989-92).

"He brings a wealth of knowledge to the position," Dantonio said on a video posted on Michigan State's website. "When you make a decision like this, you have to look to your players, the chemistry that we've created here among our staff, also the chemistry of our football team, have to look at the terminology and the things we've done. You want to try to keep things as much the same as you can for our players so they can continue to play fast."

Roushar will continue to coach Michigan State's offensive line. The team will hire an assistant to work with the wide receivers, a group Treadwell oversaw.
