how do you define that and what data do you have to support that?

I think Bronco in general was more conservative in his approach and relied on a bend but don't break approach, he picked his spots to be aggressive but not get beat deep or give up big plays (deep cushions by his DB's), tried to make teams put together extended drives, he'd often punt when drives stalled on opponents 30+ yd line to play the field position game rather than risk missing a long FG, etc.

At least in general this was his philosophy. Not aggressive, very practical, but he wasn't against bringing pressure on a key 3rd down when it was an obvious passing down (maybe when opposing offenses got in the red zone, etc). Bronco was good at mixing up his coverage looks to confuse opposing QB's and was good at mixing up his blitzes so it wasn't predictable and would use stunts, delays, bring up a DB to rush, etc.

Tuiaki employs a similar philosophy in some ways but we will kick FG's when drives stall near opponents 30 yd line and I think he's a little more judicious when it comes to bringing pressure (or at least it seems that way) but is really good at mixing up his coverages to confuse opposing QB's.
