Jim Harbaugh is returning to Michigan’s sidelines this weekend after fulfilling his 3-game suspension to start the year. He returns for a matchup against Rutgers but was asked about JJ McCarthy’s performance from Week 3 at his press conference.

That performance against Bowling Green included 3 interceptions — McCarthy’s first picks of the season — after a dramatic start throwing the ball. Harbaugh admitted sooner or later that’s going to happen with discussions of a “touchdown to incompletions” ratio unlikely to hold up over the season.

“Scary good is where you want to be, but law of averages is going to catch up at some point. You do what you can to keep those balls in the air, they want to come down,” said Harbaugh at his weekly press conference. “Where were we? Where were we just at? We were comparing touchdowns to incompletion ratio. We weren’t talking touchdowns to interceptions because there hadn’t been any. There’s no way that’s gonna continue, it’s not gonna happen that way.”

Harbaugh went on to say he wants to see players maintain confidence and aggression on the field but noted “precautions” still need to be taken. That’s especially true as related to turnovers and ball security.

“You want confident, you want aggressive, optimistic that things are gonna wok out… Some precautions gotta be taken, some risks avoided,” Harbaugh explained. “Turnovers, the ball, ball security.”

Even with his 3 interceptions, McCarthy is still completing 82.4% of his passes for 701 yards, 7 touchdowns as Michigan prepares for the B1G opener. He’ll look to bounce back against Rutgers this Saturday.
