Man, I could almost cry watching it.
In the last press conference, Hetherman said he counted 20 missed tackles resulting in 100+ additional yards.
If this team can just get back to tackling better and fix absolutely nothing else, the passing yards allowed ranking could go from #122 (283 passing yards per game) to somewhere around #75 (160 passing yards per game) overnight.
That's a difference of 123 yards and at least 2 scores.
For context, last season's defense ranked #60 in passing yards allowed.
Now combine that with the #1 run defense and the high scoring #1 offense, and this team would beat anyone in the top 25 by a minimum of 14 points.
