How frequently do top 5 coordinators become available as coordinators? Teams tend to hold onto those guys, and if they are doing well, they tend to want to stick with it until a HC job opens up.
We went out and spent $ on Greg Roman a couple of years ago, who had been pretty well respected around the league.
I think Leslie Frazier is promising on D. Unfortunately it seems like pretty slim pickings on the Offensive side (McCoy was the only name I would have been excited by, and it seems he really wanted to be back in Denver.)
