I think partially because the NFL is so specialized. Most positions are mutually exclusive to one another, and don't really give anyone full coverage of the team dynamic like soccer or basketball would. Even a QB probably can't convert much of their knowledge to the RB position, for example.
Coaching staffs in the NFL are enormous. Head Coach, OC & DC usually take the spotlight, but every team also has dozens of positional or unit coaches (like a defensive line coach) for the reasons above.
Your playing experience doesn't transfer over cleanly to a Head Coach position in the NFL because Head Coaching is closer the executive level of things than I think most people realize. It's more to do with personnel decisions, PR, and being an overseer to a large staff, with some also taking on the direct play-calling and training duties.
Also like everyone else mentioned, coaching is a lot more work for a typically less lucrative job. I would wager Messi or Ronaldo won't be working 80-100 hour weeks when they do eventually coach.
