Tomlin's approach is to try and hang around and win it in Q4. He's said that almost verbatim, probably a few times.
So in an offensive league, scoring points and jumping out to a lead is somewhere around priority #5 for Tomlin. That will put you in the hunt for 9-10 wins, but does little to prepare the team for playoff opponents. And that's what the people really paying attention have come to accept until PIT gets a new HC.
Also, for being such a "good coach", Tomlin has NEVER had a coach he developed hired by another team. He has NO coaching tree - no one hiring his people because they like what PIT does and want to copy it. Me thinks most of the league realizes those two SBs are more attributable to Cowher's coaches and players than Tomlin.
Media loves the guy, though, which is where most of the hype comes from. What he's put on tape tells a different story.
