Watching this reminded me of being at the 2018 Miami game.
Great defense that overpersued to make big hits and just flat missed tackle after tackle, turning short 2-5 yard plays into big gashes. Not as many HUGE plays given up in '06 SB as MIA, but similar frustration for a D that was solid as fuck and shouldn't give up big chunks via tons of missed tackles.
That said, the ineptness of the Bear's O, this SB should not have been as close as it was. Call Hester TD & Grossman's pick 6 a wash on the scoreboard.
Still, with such a terrible turnover margin against, it was within reach had the O been only up the level of quasi-average & not predictable as hell. That's what I fear for current Bears all over again.
