When all is said and done as far as Buffalo Bills head coach Sean McDermott is concerned, there’s likely to be more “culture shock” than “culture change” coming to One Bills Drive. Players on both sides of the ball clamored for more discipline and accountability ever since previous head coach Rex Ryan was fired in late December.

Remember the phrase, “be careful what you wish for”? If players wanted more discipline, structure and accountability, they just got it and then some with the type of positional coaches McDermott’s has hired so far.

Throughout the 17-year playoff drought, the level of talent on Bills rosters has varied a great deal. For example, former head coach Chan Gailey made the most out of an offense consisting of middling talent Stevie Johnson as the number one wide receiver, quarterback Ryan Fitzpatrick, as well as running back C.J. Spiller. Undrafted free-agent running back Fred Jackson was arguably the most gifted player on offense at that time.

However, the level of talent drastically improved over the last few years through the draft and free agency. Despite injuries to key players during 2016, Buffalo still had a better offensive line, depth at running back, and defensive line by comparison to Gailey’s journeymen.

Under Rex Ryan, the Bills failed to do much better in terms of overall record despite having a top-three NFL running back in LeSean McCoy, an elite wide receiver in Sammy Watkins (when healthy), and a quarterback who is not necessarily elite but much less likely to turn the ball over as much as Ryan Fitzpatrick did.

The reasons for underachievement by these more talented squads can be certainly be debated, but there’s no question Buffalo was not getting the kind of productivity on the field reflective of their lavish spending to the cap.

The Bills organization clearly knew after the Rex Ryan experiment failed they needed to go in a different direction in terms of the type of personality and temperament of their head coach. Ryan was laid back and allegedly behaved more like he wanted to be friends with players than their head coach.

Hiring Sean McDermott definitely put an exclamation point on going “all-in” to find the “anti-Rex”. Whereas Ryan was loose and unorganized, McDermott appears to be the exact opposite. Furthermore, in hiring defensive coordinator Leslie Frazier and especially defensive line coach Mike Waufle, McDermott is doubling down on the organization’s desire for more accountability and discipline. Neither are exactly known for their “warm and fuzzy” personalities.

Time will tell whether veering so much in coaching philosophy and personality will be the answer the Buffalo Bills are looking for to make a return to relevance in the NFL. There’s no question McDermott and his coaching staff are the polar opposite of his predecessor with respect to discipline and accountability.
