Michigan offensive coordinator Tim Drevno discusses the competition at quarterback, shuffling along the offensive line.

Jake Rudock was the new version of "one and done," a graduate transfer teleporting from Iowa to Michigan for a stellar 2015 season.

Now removed from Ann Arbor to pursue an NFL opportunity, replacing Rudock becomes the single most important focus for the Wolverines heading into 2016.

Now less than a week into spring football practice down in Florida, offensive coordinator Tim Drevno isn't anywhere near announcing the quarterback likely to fill Rudock's shoes this fall.

"We'll see as it goes," Drevno told reporters. "Jim (Harbaugh) and I will talk about it and as we go here we'll see how it progresses. Right now it's, we're going to day four, close week one tomorrow night and head back to Ann Arbor and we'll see and talk about it as a coaching staff. 

"You just don't say by week two we're going to do this. It's really a feel deal as coaches and you watch film, get comfortable with guys, you progress in your own way."

Thought to be the obvious choice down the line is Houston transfer John O'Korn who will have two years of eligibility after sitting out the 2015 season.

O'Korn threw for 3,117-yards and 28 touchdowns as a freshman at Houston, ultimately losing his job after starting the first five games of his sophomore year.

"I like John," Drevno said. "I think John's a really competitive person and it's important that he wants to do things right. He has really good leadership in the huddle, like all of those guys. 

"Shane Morris is doing a nice job, Wilton (Speight) is doing a nice job. (Alex) Malzone, Brandon Peters, I mean you look at him when he walks out, he's a beautiful looking specimen."

OL Coming Together

If Rudock's replacement is priority No. 1 for Michigan, next up on that list will be the starting center position vacated by possible first round NFL draft pick Graham Glasgow.

In response, the Wolverines have toyed with junior Mason Cole at center, starting 25 games at left tackle in his short career thus far in Ann Arbor.

"I like what Mason is doing," Drevno said. "I think in spring ball you roll out the balls, you try different people in different positions. 

"It's not like you're playing a game on Saturday so you try to see where people fit best. I'm really pleased with what he's doing and Pat Kugler's doing a nice job."

Shuffling positions isn't a new concept to Drevno, just a year ago sliding Ben Braden from right tackle to left guard while Erik Magnuson, who spent much of his career on the interior, started 12 games at right tackle.

The key, Drevno says, is finding the five guys that work the best together regardless of position.

A major area of growth through three practices this spring is simply in knowledge up front, and not just an understanding of their positions on the offensive line, but also efforts to pay better attention to opposing defenses.

"Just the next level of what happens if they're in an odd front or an over front?" Drevno said. "What happens if the safety comes down, do we need to make this call? It's a lot more where I say their football lens is opening. 

"Which is really neat and it's really rewarding just as a coaching staff when people are really catching on to what you're trying to teach and want to be good at it."

One intriguing player to keep an eye on this spring is sophomore left tackle Grant Newsome, a 6-foot-7, 300-pounder that made four appearances and one start in 2015 as a true freshman.

"He's gotten stronger," Newsome said. "Kevin Tolbert and his staff have done a great job. You can see the maturity in his eyes. He's doing good. He's right on schedule and he's doing a good job, really is."
