Still in his practice uniform, Blake Corum stood in front of the lectern at Schembechler Hall and paused, gazing into the distance.
He was contemplating what Michigan football's biggest upgrade on offense was, considering the Wolverines have statistically been more productive then last year's Big Ten championship offense.
He could have chosen quarterback J.J. McCarthy, who's protecting the ball as well as Cade McNamara did a season ago but completing passes at a higher rate and making more plays with his legs. He could have pointed out Olusegun Oluwatimi, a second-team All-American center a year ago with Virginia who might be the best lineman on U-M's dominant unit this year.
