This is from a Dled report, so take that into consideration, but it's what we all assume to be true.
Upgrading at QB Coach to Knapp over Bush Hamdan should help. Steve had a short offseason last year with his late hire, but if he didn't spend the last 360 studying NFL Offenses and getting ready, and we don't get back to the top of the offensive charts early, Sark may not make it through the year as playcaller.
We all need to be rooting for him, because as he goes, likely goes our season.
