​ANN ARBOR — Two simple words — do more — invigorated and inspired the Michigan football team last week during meetings and practice following a narrow win over Western Michigan in the season opener and ahead of a big matchup against Southeastern Conference opponent, top-10 Oklahoma.Those words were Michigan head coach Kyle Whittingham’s contribution to the players after they held a meeting a day after winning the opener. He said the Wolverines embraced the mantra and so did the coaches. Whittingham joked he worked 100 hours last week, not 90 in an effort to “do more” but more importantly, the coaches stepped up the physicality of practices, and, well, they did more.The result was a 17-10 upset of Oklahoma last Saturday, Sept. 12, to move Michigan to 2-0 and and higher in the national rankings. The Wolverines are 19th in the Coaches’ and AP rankings after dropping out of the latter after the WMU win. Michigan’s final non-conference game is Saturday, Sept. 19 against UTEP, which Oklahoma defeated, 51-0, in Week 1.“The mantra last week was ‘do more’ in every capacity,” Whittingham said Monday, Sept. 14 at his weekly news conference. “Do more with your nutrition. Do more with your hydration. Do more with the weight room, and they answered the answer the bell. We took that to heart.“Practice was more physical than it was the week before. The week before, we had had a longer lead in (coming out of preseason camp), and we ramped things down a little bit closer to the game.”Whittingham called the win over Western Michigan, which took a Hail Mary after one second was added to the clock, as a “wakeup call” for the staff and players. Hence, the move to more physical and intense practices.“More hitting, more finishing blocks, more contact drills,” Whittingham said, describing how practice intensity was turned up.In no way is Whittingham satisfied with where this team is two weeks into the season, although he praised the defense and punter Cam Brown, who has been a field-position weapon. He described the offense as a work in progress with sophomore quarterback Bryce Underwood, who had an improved performance from Week 1, still taking shape; Jordan Marshall and the run game still not in a rhythm; and the receivers, particularly Andrew Marsh, not yet making a big splash.Offensive coordinator Jason Beck made Underwood running a priority in the game plan against Oklahoma. He led the team with 18 carries for 87 yards, including a 38-yard touchdown.“We can’t go too crazy with it,” Whittingham said of running Underwood, because there’s a finite amount of times you can carry the ball, and you put yourself in harm’s way too much and something will happen that’s not good.”Michigan’s emphasis will be on establish the run with the running backs. Marshall, the team’s top returning rusher, has not yet found his rhythm. He had 32 yards on 11 carries and scored on a one-yard run on the go-ahead touchdown against OU. On the next
