2020 playoffs coaching trees
 

Patriots/Belicheck tree 3. Belicheck, Vrabel, O,Brien
Reid Tree 4, Reid, Harbaugh, McDermott, Pedersen
All others 5, Peyton, Shanahan, Carroll, Zimmer, LaFleur.

That's pretty impressive. Fully one third of the playoff teams are from the Reid tree. One fourth are Patriots tree. Is it any wonder why these teams are always getting coaches poached? Plus, Reid has more coaches in the playoffs than the Patriots.
