Detroit Lions center Dominic Raiola probably would not have objected to an endorsement from coach Jim Schwartz or general manager Martin Mayhew today.

The Lions spent this week doing some house cleaning. They released receiver Titus Young, who was problematic, cut defensive end Kyle Vanden Bosch to save money, plus released guard Stephen Peterman.

Raiola is a player teetering on the danger zone.

The 34-year old center just completed his 12th NFL season. Raiola was solid last season, but according to ProFootballFocus, he allowed 12 quarterback hurries, eighth most in the NFL. He only allowed two quarterback hits (eighth best in the NFL) and three sacks (tied for fifth most).

When asked about Raiola's future, Schwartz did not confirm his center's spot on the 2013 roster.

"Our roster is still a work in progress," Schwartz said. "We're preparing right now for free agency. We got back from the Senior Bowl when we were working on draftable players this year. We're balancing right now as a coaching staff, working on all our cut-ups and evaluating those. I think I said this before, a lot of times you get a little different perspective of players from the end of the season. The way you felt the day after the season and month later when you've got done all your cut-ups, and things like that, free agency, and the draft.

"It's always a work in progress. Martin's famous for saying there's no finish line when it comes to your roster. I'm sure there will be other things that we do, but these other ones came up right away. Different things with each of those moves."
