The last Saturday in September will be the last chance for Big Ten teams to work out their kinks before conference play begins.
Minnesota is desperate for more offense. Nebraska needs better play from its defense. Even defending national champion and top-ranked Ohio State has problems.
The Buckeyes' most talked-about issue, of course, has been quarterback. Just as disconcerting to coach Urban Meyer have been the struggles of the players around Cardale Jones and J.T. Barrett.
Meyer, whose team hosts Western Michigan ahead of its conference opener against Indiana, is looking for improvement in all areas from an offense that accounted for 13 points and five turnovers in last week's 20-13 win over Northern Illinois.
