Coaching changes occur every NFL offseason, and this year is no different. With new coaches, changes in philosophy and schemes on both sides of the ball appear. Let's take a look at the teams affected by this turnover with entirely new staffs plus the teams that had a shift at either offensive or defensive coordinator. As a note, it's clear that many defenses don't exist within a traditional base look -- a 4-3 defense won't be in that set all the time. What this reflects is the ideal set each coach likes to run.
Completely New Staff
Indianapolis Colts | Chuck Pagano (Head Coach)
This team will bear little resemblance to the Colts we've seen in the past on both sides of the ball. Offensively, coordinator Bruce Arians will oversee a much more physical unit, one that uses better size. The team will want a dominating run game, but Arians knows how to emphasize a sophisticated passing game. We will see bunch formations, multiple-receiver/tight end looks and the occasional no huddle -- all things that Andrew Luck can run. On defense, Indianapolis will transition from an athletic 4-3 look to a more physical 3-4 front with two-gap principles. On the back end, the trademark Cover 2 defense that we have seen for years will be replaced by aggressive man schemes with some press looks.
