Listen, it's an accomplishment to beat up on non-competitive teams as it's not something that's been all that regular an occurrence in recent years and we still have plenty of them on our schedule to rack up some wins, which is really all that matters. I have no idea how good Duke is but they were a decent benchmark in terms of talent.
The arrow up moment this week was the recognition of what works for us by the coaching staff and the continued improvement in tackling. If we can run and the other team isn't good at passing the ball we should do well. Buffalo just beat a haphazardly ranked team, go beat them and take another step forward.
In fact, win at least 4 of these next 5 home games, secure a bowl bid in October (plus or minus a day). Then take your shot at a winning season.
