Offensive line coach: Paul Alexander, Bengals
One of the longest-tenured assistants of any stripe in the NFL, Alexander has been the Bengals’ offensive line coach since 1994, and added the title of Assistant Head Coach in 2003. He’s served under four different head coaches for the Bengals, and his lines have blocked for four different running backs with 1,000-yard seasons. Cincinnati’s line under Alexander has ranked among the top 10 in fewest sacks allowed totals in four of the last five NFL seasons, and it set franchise records for low quarterback takedowns in two different seasons before that. Alexander has gotten the job done with his front five through multiple personnel shifts, injuries, coaching philosophies, and schematic shifts in the league. At this point, he should be talked about in the same breath as legendary line coaches like Howard Mudd and Alex Gibbs.
