Whenever a coach walks into the meeting room with three Super Bowl rings, players are more apt to pay attention and heed the message. Thus, it is not a surprise that Crennel has consistently put together elite defenses over the past decade-plus as a head coach and defensive coordinator. The wily play caller features a 3-4 base scheme that is predicated on reading and reacting, but the system features a number of checks that allow players to get into ideal play calls based on formation tendencies. Crennel is one of the best in the business at forcing an opponent to play "left-handed" (take away the offense's most important threats or favorite plays) and rely on role players or unscripted plays to move the ball down the field. The strategy worked to perfection during his inaugural season in Houston, with the Texans leading the NFL in takeaways and emerging as a defensive force in the second half of the season. With J.J. Watt also enjoying a historic season under Crennel's direction, it is time to give the Texans' defensive leader props for his extraordinary defensive acumen and superb game planning.
