Josh McDaniels learned a lot from Bill Belichick.
Prior to being named the head coach of the Denver Broncos, McDaniels had only served under one head coach: Belichick. They were together for almost an entire decade, and Belichick became a mentor to McDaniels.
In fact, Belichick even wrote up a document to teach McDaniels how to become a successful head coach. To say that he's learned a lot from Belichick would be an understatement.
After his stint with the Broncos, though, you can also say that he learned too much.
Belichick is a throwback to coaches like Tom Landry. They're not very personable with their players. They also believe that their system is the main reason for team success.
McDaniels brought that with him from the New England Patriots. He had issues with quarterback Jay Cutler and wide receiver Brandon Marshall. He willingly allowed good players to leave, believing that he can find other pieces for his system.
McDaniels believed in himself so much that he did not want experienced and vocal coordinators around him (defensive whiz Mike Nolan was inexplicably forced out).
The 34-year-old Ohio native also infamously emulated his mentor by being involved in a practice taping scandal.
When you're Belichick and you have three Super Bowl rings and a 70 percent franchise winning percentage, the act will be tolerated. When you're someone who doesn't have as prolific of a resume, then it simply is not going to work.
