Half the teams in the NFL learning new systems on offense

While the New York Jets are scrambling to get up to speed on the scheme of first-year coordinator Tony Sparano, 15 other teams are also putting together new systems on offense.

That’s right, half of the teams in the NFL have new offensive coordinators. Here are the others:

Todd Haley, Pittsburgh — The former Kansas City coach returns to the Steelers, where his father, Dick, ran the personnel department during the Super Bowl years of the 1970s.

Bruce Arians, Indianapolis — Arians goes from working with Ben Roethlisberger in Pittsburgh to Colts rookie quarterback Andrew Luck, the No. 1 overall draft pick.

Brian Daboll, Kansas City — Daboll and Romeo Crennel worked together on Bill Belichick’s staff in New England. Now Daboll can build around running back Jamaal Charles.

Josh McDaniels, New England — After bumpy stints with Denver and St. Louis prompted him to return to the Patriots, McDaniels takes over for Bill O’Brien, now at Penn State.

Tom Clements, Green Bay — This is a promotion for Clements, but not a change of scenery. He was bumped up from quarterbacks coach to succeed Joe Philbin, now Dolphins coach.

Bill Callahan, Dallas — Jason Garrett will still call the plays for the Cowboys. Callahan will coach the offensive line, taking over for the retired Hudson Houck.

Mike Sullivan, Tampa Bay — Sullivan coached wide receivers then quarterbacks for the Giants, picking up a pair of Super Bowl rings. He’ll try to re-create that magic.

Brian Schottenheimer, St. Louis — Schottenheimer, who spent the last six seasons with the Jets, will try to help quarterback Sam Bradford take the next step in his development.

Hal Hunter, San Diego — Hunter is a former college coach who broke into the NFL as offensive line coach of the Chargers in 2006. He was promoted to replace Clarence Shelmon.

Mike Sherman, Miami — Sherman gave Philbin his first job in the league — as a Packers assistant — and was once his high school English teacher.

Greg Knapp, Oakland — Knapp was Raiders offensive coordinator under Lane Kiffin, then Tom Cable, but spent the last two seasons coaching quarterbacks in Houston.

Dirk Koetter, Atlanta — Koetter will bring “a fresh set of ideas” to the Falcons, Coach Mike Smith said. Still, Koetter’s unit in Jacksonville finished last in total offense in 2011.

Mike Tice, Chicago — Tice, promoted from coaching the offensive line, is an offensive coordinator for the first time and takes over for the fired Mike Martz.

Bob Bratkowski, Jacksonville — Bratkowski is reunited with Jaguars Coach Mike Mularkey, his staff-mate in Atlanta. The challenge: turning Blaine Gabbert into an NFL quarterback.

Brad Childress, Cleveland — Childress and Browns Coach Pat Shurmur spent seven years together on Andy Reid’s staff in Philadelphia.
