No, we're not in meltdown mode. We've lost one game that we definitely should have won (USD), one that we had should have had a good chance to win (NIU), and one that most people thought we wouldn't win (USC). Things aren't looking good for a successful Big Ten season, but at this point the wheels haven't come flying off the bus... yet.
If Bruiniks and Maturi had a longer time horizon than the next year or so, then I agree Brewster would likely be gone after this season barring a very good showing in conference play. I'm not saying that winning 3-5 games is good enough for any coach to feel safe in his job. I'm just saying that under the current circumstances it's probably just enough to allow Bruiniks and/or Maturi to kick the can down the road and let the next guy deal with the issue.
As far as expectations go, I'm not happy with the team's current record, I want them to play better and I want them to win more. I am hoping that the defense starts tightening up as the season progresses and the kids get more experience. It may happen, it may not. Unless our D improves drastically our main hope for winning games looks to be through ball-control, and unless we can 'pound the rock' better in future games than we did in the last few, it's going to be a long(er) season.
