Jim Bob Cooter
The Lions are reportedly expected to keep Jim Bob Cooter on their coaching staff with Matt Patricia as their new head coach, but he would likely be willing to take a head coaching job if offered.
Cooter was an assistant coach for the Colts from 2009-11, and he could make a return to Indianapolis as a head coach. Cooter worked wonders with Matthew Stafford in Detroit, and he could do the same with a quarterback as talented as Andrew Luck.
Here is his complete candidate profile.
