Rumors swirling surrounding Michigan and USC offensive line coach Tim Drevno

It appears that new head football coach Jim Harbaugh is not wasting any time assembling a staff at Michigan.

The rumor mill and Twitter is starting to swirl with the possible rumors of current USC offensive line coach Tim Drevno heading to Michigan.

First mentioned by the Sacramento Bee, Drevno was expected to follow Harbaugh to Ann Arbor despite only spending one year at USC.

The rumor mill further churned when USC offensive lineman Zach Banner tweeted his goodbyes to Drevno.

"I am happy for Coach Drev and wish him luck with his new job because he deserves it," Banner tweeted. "He has a great opportunity. I love that guy."

That opportunity appears to be Michigan.

According to Scout.com's Gerard Martinez, it also appears to be an expanded role as well.

"Hearing USC offensive line coach Tim Drevno will become the offensive coordinator for Jim Harbaugh at Michigan," Martinez tweeted Wednesday.

Drevno has spent the majority of his coaching career following Harbaugh to each stop. He was an offensive coordinator at San Diego from 2003-2006, followed Harbaugh to Stanford to coach the tight ends for the first two seasons and switching to the offensive line.

Drevno also coached with Harbaugh with the San Francisco 49ers handling offensive line duties before heading to USC after the 2013 season.

This is a developing story.
