Eight new head coaches will patrol the sidelines once the 2013 NFL season begins. Here is a worst to first ranking of each of the eight new hires.
Chip Kelly, Philadelphia Eagles
Chip Kelly's u-turn from Oregon and the Philadelphia Eagles decision to hire him, was one of the strangest moves on the coaching carousel.
Kelly came to fame at Oregon running a high concept, read-option offense. That's a pretty big change for an Eagles team that has run some version of the West Coast offense for nearly two decades.
There's also the small matter of a potential schematic change on defense. Kelly has hinted at using a 3-4 and that will mean a major overhaul for a defense loaded with 4-3 personnel and concepts.
Many may feel the Eagles need bold changes. However, Kelly's hiring may key a transition too dramatic for a team still talented enough to compete in the NFC East.
Gus Bradley, Jacksonville Jaguars
Gus Bradley seems like a bizarre choice for the Jacksonville Jaguars. After all, the ex-Seattle Seahawks defensive coordinator is joining a team crippled by its woeful offense.
There were plenty of young offensive minds for the Jaguars to pursue. Instead they are hoping Bradley can base his rebuild on a strong defense. He did some good work in Seattle, however, he did have the benefit of working with a defensive-minded head coach in Pete Carroll.
Tasking Bradley to emerge from that shadow and work on his own, is a tall order. It could be too much for a young, first-time head coach to handle on a team that was 2-14 in 2012.
Rob Chudzinski, Cleveland Browns
Having just slumped under the guidance of a young, unproven ex-offensive coordinator, the Cleveland Browns strangely hired another one. Rob Chudzinski replaces the outgoing Pat Shurmur, giving the Browns the same formula they chose in 2011.
Coordinators like Ray Horton and Norv Turner will be a boon to Chudzinski. However, that might not be enough to turn around a team that has been a loser since re-entering the league in 1999.
Doug Marrone, Buffalo Bills
Former Syracuse head coach Doug Marrone isn't the marquee name many Buffalo Bills fans might have wanted after 13 years without playoff football. What the Bills have done is taken another chance with their top job.
Marrone's expertise is on offense and that makes him a poor fit for a team blighted by consistent struggles on defense. Marrone has weapons on offense, but can't afford to overhaul both sides of the ball.
Bruce Arians, Arizona Cardinals
The Arizona Cardinals can be happy with their choice to hire Bruce Arians. His record of helping young quarterbacks flourish is a huge boost to a franchise that has been wrecked by problems under center.
Arians turned Ben Roethlisberger and Andrew Luck into stars. However, doing the same for Kevin Kolb will be the biggest challenge of his career. Arians has a solid defense and also offers some useful experience, after guiding the Indianapolis Colts for much of last season.
Marc Trestman, Chicago Bears
Just like the Cardinals, the Chicago Bears choice of new head coach was the best decision for their quarterback. Trestman's knowledge of the West Coast offense can get Jay Cutler's career back on track.
With a strong defense already in place, Trestman is the right man to design an offense to suit personnel like Cutler, Brandon Marshall and Matt Forte.
Andy Reid, Kansas City Chiefs
After four years gambling on head coaches, the Kansas City Chiefs did the right thing hiring Andy Reid. The Chiefs need a proven winner and stability. Reid offers both.
Not only does he boast a track record of consistent winning, Reid has gotten the most from his quarterbacks. That's great news for a Chiefs teams with huge question marks at the position.
Reid's efficient West Coast-style passing game could make a success of Matt Cassel, or help a rookie quarterback make a fast start. Reid will revitalise a struggling offense and trust his coaches to run the defense.
Reid's presence on the sidelines makes the Chiefs credible again for the first time in a long while.
Mike McCoy, San Diego Chargers
The San Diego Chargers hiring Mike McCoy was the best hire of the coaching carousel. The Chargers needed a coach who could get quarterback Philip Rivers back to his best. McCoy is the perfect fit.
His track record shows a coach capable of successfully tailoring a system to the specific attributes of his quarterbacks. As offensive coordinator with the Denver Broncos, McCoy did that first for Tim Tebow and then for Peyton Manning.
If McCoy does the same for Rivers, the still-talented Chargers will soon be relevant again in the AFC West.
