I have to chuckle over this comment ....... fans scream for a more aggressive, press-type of coverage, Ash implements it, three mental (not schematic) errors by young players and the whole defense is crap in your eyes .... Wow !!
Take out the three mistakes and the Bearcats have 131 yards passing and less than 75 yards rushing. Vonn Bell turns his head (he had decent coverage) and he at least knocks the ball down or picks it off - Powell doesn't bite on the fake slot screen and Gunner has to eat the ball, but instead hits the skinny post where Powell should have been - Apple just got beat off the line, period. The last one (Apple) is going to happen from time to time when playing press coverage and the safety jumps a short route late in a quarter. NONE of those TD's had anything to do with scheme or system. They were a result of players making mental mistakes, being too eager to jump a route or just plain getting beaten by a very good receiver.
What I see very differently from last season (there are no roses on my glasses) is the fact that we have people around the ball in position to at least make a play. I see that we're not getting chewed up by the infamous screen passes (LB pursuit, even without Shazier) has been much better on those plays. Finally, I am seeing fewer missed tackles than I've seen in the last three seasons.
Press coverage is going to result in big plays - in BOTH directions. Kiel is the best QB we'll face this regular season, with some of the best receivers (when Tubby says it's the best group he's ever coached, that's saying something) in the country.
So my advice is to move on from the 3 plays you based your opinion on about the defense and take a closer look at the entire body of work that's been done during the off-season. This is a better defense that's also trying to break in some new talent in the secondary - a little patience will go a long way towards a stellar defense by season's end ...........
