EAST LANSING, Mich. -- For nearly a season and a half, Michigan State leaned hard on its defense to try to win games while the offense sputtered.

That pattern finally changed midway through last season, as Connor Cook settled the quarterback position, Jeremy Langford developed into a star at running back and the receivers started making tough catches. Heading into 2014, a new paradigm could be in play. The offense returns the vast majority of its production while the defense must replace stalwarts such as Darqueze Dennard, Max Bullough, Denicos Allen and Isaiah Lewis.

Nobody is expecting the Spartans defense to fall off a cliff, especially with Pat Narduzzi back at coordinator and plenty of fresh talent ready to step forward. But if that side needs time to find its footing early in the season, things could be OK.

"Our defense has obviously been very, very strong," offensive coordinator Dave Warner said. "But as an offense, we want to be able to carry this football team if need be. And do it right from start, rather than wait until four or five games into the season to get it figured out."

Michigan State isn't suddenly going to turn into Baylor or Oregon -- "I still think you've got to play well on defense to win championships," head coach Mark Dantonio says -- but there's reason to believe that an offense that averaged a respectable 29.8 points per game during Big Ten play could continue moving forward.

Cook is back and should ride a wave of confidence following his MVP turns in the Big Ten championship and Rose Bowl games. The Spartans did lose Bennie Fowler, who led all receivers with 622 yards and six touchdowns, but they return every other pass-catcher of note and expect bigger things out of guys such as Aaron Burbridge and R.J. Shelton, as well as DeAnthony Arnett. Langford, who ran for 1,422 yards and scored a Big Ten-best 19 total touchdowns, added about five pounds of muscle this offseason.

"I think it helps with my durability," he said. "I can take a hit and bounce off a couple tackles. I still feel fast, and I feel stronger now."

Michigan State was young at tight end last season and didn't utilize that position a lot, though Josiah Price made a crucial touchdown catch against Ohio State in the league title game. Tight end could become a strength this year with Price back and spring head-turner Jamal Lyles, a 6-foot-3, 250-pound potential difference-maker.

"We're better right now at tight end than we were at any time last year," Warner said.

Warner also wants to find ways to use tailbacks Nick Hill, Gerald Holmes and Delton Williams. And don't forget quarterback Damion Terry, whose athleticism could lead to several possibilities.

"We're experimenting a little bit right now," Cook said. "I feel like some new things will be added to our arsenal on offense."

The biggest question marks for the Spartans on offense are on the line, where they must replace three senior starters (Blake Treadwell, Dan France and Fou Fonoti) from what might have been the best O-line in Dantonio's tenure. The line doesn't have as much depth this spring as the coaching staff would like, but veterans Travis Jackson, Jack Conklin and Jack Allen provide a nice starting point. Donavon Clark and Connor Kruse have played a lot as backups, and Kodi Kieler is expected to make a move up the depth chart.

"We need to get that offensive line back in working order," co-offensive coordinator Jim Bollman said.

Overall, though, Michigan State feels good about the state of its offense. So good that maybe the defense can lean on it for a change, if needed.

"Last year, we got off to a horrible start and didn't really get going until Week 5," Cook said. "We don't want to have that happen ever again. With the offense we have and what we proved last year, we want to get off to a hot start and get the rock rolling early. That's what everyone on our team offensively has in mind."
