I hope not but I do think this cold be the week where we start hearing some boo's from Husker fans against the team.
Frankly, after attending almost every home game from 1972 through 2012, there were only a couple of times when I heard any meaningful boos of the team. Now I heard many boos for various coaches, refs, opposing teams, TV people, politicians, etc. But almost NEVER a team. The times were when it was clear the team had quit trying - in blow out losses (Callahan, Frank, Bo). The biggest boos I remember ever hearing in an Osborne coached game were following the 2nd quarter TD drive by back up QB Frankie London who came in after the first quarter of action of Scott Frost the game following the disasterous first start for Frost in 1996 in Arizona when he played so poorly and we lost for the first time in a couple years! Most fans knew - it was obvious as everyone knew how Osborne thought - that Tom had pulled Frankie London when he did TOO WELL in leading the team right down the field for a TD. Frost had played so poorly for his first 5 quarters of playing and London came in a fired up the team and crowd. We scored in about 5 plays, Frankie was overjoyed and so were the fans. Tom immediately put Frost back in to prevent Frankie from looking too good as Tom knew it would create a backlash and a "QB controversy" as fans always pull for the back up to get a chance and Frost (now already nicknamed "Frosty the throw man" for seemingly throwing the Arizona game (many speculated he had gambled on the game.).
To your point, I don't see any possible way of booing 'the team' but perhaps some boos for Eichhorst, Riley, and even perhaps Alex Lewis as he is not making any new fans I am certain. The team itself does NOT get booed in the stadium that I have ever seen unless it is clear it has quit trying. About twice.
