It is worth pointing out Tomlin inherited a good team from Bill Cowher, and won a title with most of the same players from that 2006 championship team. Harbaugh inherited a mediocre team from Brian Billick that had just gone 5-11 and was seven years removed from a Super Bowl. He turned it around to the point they’ve been in the postseason every year he’s been their HC, and are now the defending Super Bowl champions.
Head to head, Tomlin leads with a 7-5 record. Three of Harbaugh’s wins came with the benefit of not having to face Ben Roethlisberger. One of Tomlin’s wins came without Roethlisberger as well.
We could argue all-day who’s a better coach, but one thing’s for certain: Takeaway Bill Belichick from the New England Patriots and Tom Coughlin from the New York Giants, and you’ve got the two most successful NFL head coaches over the past 5 seasons.
