Yeah, D-line is the key concern. I agree. There's been a bunch of emphasis put on "creating havoc" this year, which is a catchy way of saying getting pressure on the QB in the backfield. The talking heads were pretty excited and somewhat hot & bothered by the dominant defensive pressure on Saturday vs. Murray State, which to me, is pretty much the equivalent of kissing your sister. Nothing to be proud of or excited about. This weekend won't tell us anything either.
Let's see how they do vs. Notre Dame. Which I know is a little early to start prognosticating, but if ND shows up to Athens with the weak sauce they brought to Louisville, then I think it's a long evening for the Irish.
