just a few notes: Joe D’Alessandris was with Gailey at GT so who knows if he will stay on or not.
Bicknell, Carthon, Muir, all have OC experience as does Defensive Q/c coach Pat Perles. So does asst GM Joel Collier. Mostly as a RB coach but was promoted to OC by Dave Wandstedt at Miami but had to give that up because of a serious illness that offseason.
Also training camp intern coaches Ritchie Anderson(TE's, WR's RB) and Anthony Pleasant (DE and OLB) are still with the team as far as i can tell from the games. It wouldn't be a big suprise to see them added for the regular season if needed. Both are Parcells and Belichick guys and former players.
