At a time of the season when the intensity is flowing through NFL buildings, Giants center Shaun O’Hara provided a little levity on Thursday. O’Hara revealed what his fellow offensive linemen throw down leading up to a game … and then throw up right before it.

First, let me applaud the work of Matt Ryan and Joe Flacco. Both did a great job of managing their teams and avoiding the rookie mistakes that you usually see at the quarterback position. That said, I think we have to be careful about crowning them the next anything. Let’s just sit back and watch.

No big news on the injury front Thursday for either the Cardinals or the Panthers. The Cardinals continue to rest WR Anquan Boldin and his ailing hamstring, holding him our for the third straight day.

Time and time again there are reminders that this is a quarterback-driven league. Now there’s another.

The Chargers added an interesting name to their injury report Thursday: kicker Nate Kaeding.

The Eagles released their official Thursday injury report, upgrading several key players who were limited in practice on Wednesday.

When Eric Mangini launched his NFL career as a ball boy at the age of 23, it was in Cleveland. When Mangini landed his first NFL coaching job, it was for then Browns coach Bill Belichick, and it was in Cleveland.

When Cleveland hired head coach Eric Mangini, it lost two general manager candiates.

Browns owner Randy Lerner decided he wanted Eric Mangini to be the man to lead his organization in the future. Why he didn’t want Scot Pioli remains a question.

The coaching carousel continues spinning. The Jacksonville Jaguars requested and were granted permission Wednesday to interview Mel Tucker for their defensive coordinator job. Tucker recently interviewed for the Cleveland Browns head-coaching job that went to Eric Mangini.

Eric Mangini has yet to be introduced as the Cleveland Browns’ head coach, but he made his first move by hiring Rob Ryan as his defensive coordinator.

On the day the Oakland Raiders lost their offensive coordinator, they also lost their running backs coach.

The Cleveland Browns have made their call. Eric Mangini is in, and Scott Pioli is out.

The New Orleans Times-Picayune reports that Reggie Bush underwent microfracture surgery on his left knee in mid-December. Saints general manager Mickey Loomis said he still expects Bush to be ready in time for the team’s first minicamp in early June, but such procedures are difficult to put a timetable on.
