Guys that might be ready to be head coaches

[Warren]

Some other assistants whose names have been mentioned as possible HC candidates:

Offense
Chargers AHC/TE coach Rob Chudzinski -- #1 offense based on yardage
Cardinals AHC/OL coach Russ Grimm -- not as much as the year the Cards won the NFC
Titans OC Mike Heimerdinger -- #1 offense based on points scored

Defense
Dolphins AHC/DB coach Todd Bowles -- Parcells protege
Browns DC Rob Ryan -- based on his twin brother's success and recent signs of life in Cleveland. The Ryan style would seem to be a "programmatic non-fit" with Bob McNair.
Bengals DC Mike Zimmer -- not as much as last year


For purposes of making the list more complete only, a few more active former HCs:
Dave Campo, former Cowboys HC, current Cowboys DB coach
Dom Capers, former Panthers and Texans HC, current Packers DC (Collinsworth was really pushing him as a candidate on SNF last night )
Gunther Cunningham, former Chiefs HC, current Lions DC
Kevin Gilbride, former Chargers HC, current Giants OC
Bobby Petrino, former Falcons HC, current Arkansas HC
Mike Sherman, former Packers HC, current Texas A&M HC

And a couple college guys who get mentioned a lot due to their NFL backgrounds:
Iowa HC Kirk Ferentz -- the Texans reportedly wanted to talk to him during their last HC search
Stanford HC Jim Harbaugh
