LOS ANGELES -- Jon Embree left his job coaching Washington Redskins tight ends to become head coach at Colorado in the second week of December in 2010. Four games remained in the Redskins' season. Chris Cooley, by that point one of the game's most productive tight ends, quickly became uneasy about what would follow. His new position coach would be Embree's assistant, a 24-year-old named Sean McVay, and Cooley was skeptical.
It took one day to reverse that.
"This 24-year-old kid came in and knew everything about the offense, and everything about everything," Cooley said.
