There are a lot of reasons to be wary of Mike Tomlin’s 17-consecutive seasons without a losing record, but it is impossible to write it off as completely unimportant. He had the benefit of working with a future Hall of Fame quarterback for most of his tenure in Ben Roethlisberger, but there have still been some seasons where he has truly had to scratch and claw his way to maintain the streak. Think back to the Duck Hodges season while Roethlisberger was injured, or either of the two Kenny Pickett seasons, for example.
Tomlin has consistently kept his teams competitive regardless of circumstance.
