Looking at the current named position coaches that have been confirmed and the remaining open positions that need to be filled. I have bolded who I think will be announced.
Head Coach: Bruce Arians
OC / Passing Game Coordinator: Byron Leftwich
OL / Run Game Coordinator: Harold Goodwin
QB: Clyde Christensen
RB: James Saxon
TE: Ben Steele
WR: Skyler Fulton
DC: Todd Bowles
DL: Kacy Rodgers
DL: Breston Buckner
LB: Mike Caldwell
LB: Larry Foote
CB: Kevin Ross
CB: Nick Rapone
SP: Amos Jones
Looking over what openings have not publicly been stated as being filled. Here are the best guesses after playing connect the dots...on Arians history.
RB: James Saxon or Stump Mitchell
TE: Ben Steele or Rick Christophel
DL: Kacy Rodgers or Breston Buckner possibly both
LB: Mike Caldwell or Larry Foote possibly both
SP: Amos Jones
Should be an interesting staff. I would also not be surprised to see Tom Moore and Tom Pratt named as special assistants.
