I am not worried at all, honestly.
It would be nice to see them playing better right now, but they could also end up wasting a hot streak that could net them 11 wins in the postseason. I know that might sound like a dumb way to look at things, but oh well.
They have the talent to beat anyone. They just need to make sure that talent is on the field once the postseason starts.
Their play in September should have no effect on their play in October.
