Michigan coach Jim Harbaugh hopes great chemistry can defy gravity.Harbaugh is pleased with the state of his program from top to bottom. It’s hard to argue, considering the Wolverines are undefeated, ranked No. 2 and have five easy wins to their credit. They will face unranked Minnesota in Minneapolis on Saturday night.Michigan (5-0, 2-0 Big Ten) easily passed its first road test last weekend, crushing Nebraska 45-7. The Wolverines have scored at least 30 points in each game while allowing a total of just 30 points. The Cornhuskers didn’t score until late in the fourth quarter after Michigan had gone deep into its bench.”When things are scary good, that’s where you want to be,” Harbaugh said. “That’s who you want to be with and how you want to be doing things.”However, Harbaugh knows every opponent will be trying to knock his team off its perch.”The law of averages say it’s going to catch up to you, to see if you can defy Sir Isaac Newton’s laws of gravity,” he said. “What goes up must come down, and the gravitational force of the earth is tremendous. So are some of the forces against a football team, things that are set there to divide a football team. The ones that aren’t divided are the ones playing in the playoffs and eventually champions.”Wolverines quarterback J.J. McCarthy has surpassed the 1,000-passing-yard mark this season while throwing for 10 touchdowns. He connected with Roman Wilson for two scores against Nebraska and also rushed for a touchdown.”He’s very consistent in what he does,” Minnesota coach P.J. Fleck said. “You can tell he’s an overachiever. He’s the ultimate competitor. But not only that, he connects with the football team.”Blake Corum, Michigan’s top running back, is averaging 5.7 yards per carry and has scored nine times.
