If the NFL has had a weasel, it has been former New England Patriots coach Josh McDaniels.
As one of the hottest assistant coaches to be hired in the 2009 cycle, one of McDaniels’ first moves when getting to the Denver Broncos was to trade starting quarterback Jay Cutler. As the Broncos started 6-2, with McDaniels celebrating the whole way, Denver collapsed with a 2-6 record down the stretch to finish 8-8.
In 2010, McDaniels was fired midseason after leading Denver to a 3-9 start. One of the biggest factors was deploying a Spygate-like operation against the 1-6 San Francisco 49ers when the two teams were practicing in London ahead of their International Series match.
