The template for top NFL coaching candidates is obvious: organizations want young, offensive-minded head coaches to keep up with the game's evolving passing concepts. Preferably, candidates have some experience either developing quarterbacks or playing the position.
Or, they just need to know the Los Angeles Rams' Sean McVay in some way.
A handful of upcoming candidates qualify.
Not every individual fits neat little boxes, though. Some of the game's best coordinators and/or position coaches aren't in their 30s and don't teach quarterbacks. This doesn't make them any less of a candidate.
