Five lessons from an interesting Saturday in the Big Ten:
1. Offenses surging in East Lansing and Columbus: OK, so the opposing defenses haven't exactly been stout. Still, it's hard not to notice the huge offensive numbers Michigan State and Ohio State are putting up. The Spartans scored 56 points in a win against Wyoming on Saturday, a week after posting 73 against Eastern Michigan. They're averaging 50.3 points per game for the season, which is ridiculous when you consider the state of the MSU offense a year ago. Connor Cook is in complete command of the game plan, and Jeremy Langford had his first 100-yard day of the season. "We have never exploded like this out of the gate with our offense," head coach Mark Dantonio said. Meanwhile, Ohio State has bounced back nicely after predictably struggling early with a new quarterback and revamped offensive line. The Buckeyes briefly set a school record for total yards against Cincinnati before losing 20 yards on the penultimate play; still, they finished with 710 yards and a school record 45 (!) first downs in a 50-28 victory. Quarterback J.T. Barrett, who threw for 330 yards and four touchdowns with no interceptions, is growing up quickly, and Ezekiel Elliott shows signs of becoming a star tailback. That's 116 points in the past two weeks for Urban Meyer's team. The competition will improve very soon, but both teams could pull away from the pack in the East Division if their offenses build off these performances.
2. Defenses carrying Wisconsin, Iowa: Things are going the other way in Madison and Iowa City. Other than the past week's shredding of Bowling Green, Wisconsin has yet to play an impressive, full game offensively. The Badgers had only three points at halftime against South Florida before they finally got on track in the second half of a 27-10 win. But Wisconsin's defense has been stout all season. Gary Andersen's team is the only FBS squad yet to give up a red zone touchdown this season, and the defense forced two turnovers against the Bulls. Iowa fans found out Saturday that C.J. Beathard isn't going to single-handedly transform an at times frustrating offense. But the Hawkeyes' D held Purdue without an offensive touchdown and allowed only 156 total yards -- and only 82 in the final three quarters -- in a 24-10 road win. If the offenses ever get revved up, both Wisconsin and Iowa will be very dangerous. Right now, at least, both are winning with defense.
3. Minnesota and Maryland are stealth contenders: Neither the Gophers nor the Terrapins generated much buzz this preseason as possible division contenders -- understandably so, given their recent histories. But both will at the very least be factors in the race to Indianapolis. Maryland is a play or two against West Virginia from being 5-0 and has shown explosive playmaking ability on both sides of the ball. Even with quarterback C.J. Brown injured in the first half at Indiana, Randy Edsall's team kept rolling behind Caleb Rowe in an easy 37-15 win -- the Terps' second straight, double-digit road victory. Minnesota thoroughly dominated Michigan in the Big House 30-14 and -- in a refreshing change -- displayed at least some competency in the running game. With their defense and the running of David Cobb, the Gophers can make some noise in the West despite a challenging final four games (Iowa, Ohio State, at Nebraska, at Wisconsin). Meanwhile, Maryland could have a big say in the East as division powers Michigan State and Ohio State (next week) have to go to College Park.
4. Bill comes due for Penn State's issues: It's never been any secret the Nittany Lions had serious deficiencies on their offensive line and, consequently, in the running game. James Franklin and his staff did a great job covering those in the first four games, all Penn State wins. But it's hard to win with those weaknesses in Big Ten play, and Northwestern -- despite its own problems of late -- exploited them in a big way during Saturday's stunning 29-6 win at Beaver Stadium. Penn State ran for only 50 total yards, and Christian Hackenberg was sacked four times while being pressured all game. Hackenberg had one of the worst games of his short career, but it was unreasonable to expect him to carry the entire offense the entire season. The Nittany Lions' problems aren't easy to fix, but at least they have a bye week coming up to search for answers.
5. Ameer Abdullah deserves to be a leading Heisman contender: Nebraska's senior running back is putting together a potential season for the ages. Against Illinois, he ran for 208 yards and three touchdowns while barely playing in the second half of a 45-14 win. That's the third 200-plus yard game for Abdullah this season, and he's on pace for 2,000 yards. The Cornhuskers are the lone remaining unbeaten Big Ten team, and they wouldn't be if not for their leader. Abdullah gets a spotlight opportunity next week at Michigan State, but he deserves all the Heisman love you can throw at him right now.
