It might not be Super Bowl or bust, but everyone in the Lions organization knows there's a lot riding on this year.

General manager Martin Mayhew acknowledged as much over lunch with local reporters at the NFL owners meetings Monday, and coach Jim Schwartz joked at breakfast Wednesday that "my kids are now just starting to talk to me again" after last year's 4-12 season.

"That wasn't a joke," Schwartz said. "(My son) was mad."

Family pressures aside, Schwartz and Co. need a major rebound this fall after failing to capitalize on the momentum of 2011's playoff appearance and ending last year on an eight-game losing streak.

This is an NFL, after all, that saw a quarter of its head-coaching jobs change hands after the season and a league designed for parity, one in which 11 different teams have represented the NFC in the past 12 Super Bowls (the Lions not included).

Schwartz, who received a contract extension last summer through 2015, said he's still not over the bitterness of last season.

"You carry everything with you," he said. "It makes you more determined. But it doesn't affect the way that you go about your work day, it doesn't affect the way that you go about planning your OTAs or getting ready for the draft.

"There's a consistency to the way we approach things, and it's not like last year we came off the playoffs and said, 'Hey, let's cut it down this off-season and let's go get a lot of three-day weekends.' That doesn't happen, and this year we're not saying, 'Hey, we're working every weekend.' We have a process, and we need to stick with it."

Process or not, the Lions have turned over a significant portion of their roster this off-season, with more, mostly minor, tweaks to come.

They waved good-bye to starting defensive ends Cliff Avril and Kyle Vanden Bosch, and 60% of their starting offensive line (Jeff Backus, Gosder Cherilus and Stephen Peterman) after returning 21 of 22 starters last year.

The decision to keep their roster in tact was largely cap-related, and this year's changes -- they signed Reggie Bush, Glover Quinn and Jason Jones at the start of free agency -- came by borrowing from future year's caps through the contract restructures of Ndamukong Suh and Calvin Johnson.
