Michigan Football: What You Should and Shouldn't Be Concerned About After Week 2

Through two weeks of the 2015 college football season, the Michigan Wolverines have a couple of concerns they need to address, but some of the team's shortcomings aren't yet a problem.

Mistakes are simply inevitable while Michigan adapts to head coach Jim Harbaugh's system and the rest of the staff's coaching style. The important part, though, is determining whether a particular weakness in Michigan's performance is an outlier or a trend.

The Wolverines' next chance to correct these mistakes comes on Saturday, Sept. 19, at noon ET against the UNLV Rebels.

Agree or disagree? Sound off in the comments section below.

Jake Rudock's Turnovers

One of Jake Rudock's biggest strengths at Iowa was his ability to protect the ball. That hasn't continued during his brief Michigan tenure.

He tossed three interceptions during the season opener, and the blame for two rest squarely on Rudock's shoulders—especially the pass that turned into the game-sealing pick-six.

Then, against Oregon State, Rudock lost a fumble while being sacked, threw one interception and also narrowly avoided another on a poor third-down decision.

Harbaugh has shown zero signs of replacing Rudock, so the senior seems to be safe in the starting lineup. After a few more multi-turnover games, however, Harbaugh might consider sending Rudock to the bench.

Verdict: Concerned

Lack of No. 2 Runner

The potential four-headed machine in the Wolverines backfield has essentially become a one-man show. De'Veon Smith has received a strong majority of non-garbage-time carries, leaving Ty Isaac and Derrick Green picking up the scraps.

Whether that's Harbaugh's plan or a reflection on subpar practices from the duo might not matter, because Drake Johnson is coming back.

Per Max Cohen of the Michigan Daily, Harbaugh anticipates Drake Johnson—who was rehabbing from a torn ACL—will be ready for a bigger role against UNLV.

Smith seems like he's "one block away" or "just needs to be a little faster" on multiple carries each game. Johnson's speed should allow him to answer to those pleas for a big play.

Verdict: Not Concerned

Receivers Not Named Darboh or Butt

In Week 1, Jake Butt and Amara Darboh each snagged eight passes and one touchdown. In Week 2, Butt and Darboh each recorded four catches. So far, the combination has accounted for 24 of Michigan's 45 completions.

Grant Perry—who deserves credit for some outstanding blocking on screens—has largely been a nonfactor as a receiver. Jehu Chesson was one step away on a couple of occasions against Utah and committed a foolish pass interference penalty last week.

How much of a problem is that? Well, there's no need to panic. Rudock is adapting to an entirely new set of receivers and cannot be expected to immediately show a connection with the whole unit.

Nevertheless, there's a bit of concern that could become a bigger problem during Big Ten action if improvement isn't seen during the final two nonconference outings.

Verdict: Tentative Concern

Pass Interference

Jabrill Peppers has been flagged for pass interference in both games this season, and the secondary has barely missed being called for a few more.

Although the penalty is rarely excusable, the concern meter—at least for now—is low here.

Last year, Michigan's defense was called for pass interference five times, but three of the flags came during the opening two games. Jourdan Lewis, who is now the team's top corner, was even tagged with a pair.

While the secondary—Peppers in particular—needs to work on getting heads turned when the ball is in the air, experience and film review should help eliminate these mistakes.

Verdict: Not Concerned

Few Takeaways

Tony Ding/Associated Press

For the second straight offseason, Michigan put an emphasis on its stout defense creating turnovers. For the second straight season, the takeaways aren't coming.

MLive.com's Brendan F. Quinn summarized it best:

"

At the midway point of the 2014 season, when this exact same story was being written, Michigan's Joe Bolden noted, 'We've really been putting an emphasis on turnovers since day one at camp back in spring ball.'

And everyone saw how that turned out.

Now it's more of the same. While everyone knows Michigan needs to create more turnovers, the hard part remains how.

"

Michigan snagged one interception against Utah on a Hail Mary as the second quarter expired—more fittingly described as, yay. The Wolverines' fumble recovery versus Oregon State certainly arrived at a timely moment, but it was the only takeaway.

Considering 10 of their opponents' first 15 meaningful drives reached the 40-yard line, the defense again resembles a bend-but-don't-break unit.

That style matches defensive coordinator D.J. Durkin's history, but a continued absence of takeaways will directly contribute to a handful of tense fourth quarters when the level of competition rises.

Verdict: Concerned
