the team felt that way - on the contrary.
Not only do you not have evidence, there is plenty of evidence to the contrary. Multiple players talking about showing up for the grind to prepare. Talking about how they understood that they were doubted and that they needed to show up and prove themselves every week.
The fact that they fell short in their tenth game - just a little, but short enough to lose - is not evidence in the slightest that they were complacent.
Sorry, not all "opinions" are equal. They just aren't. You just saying you think a thing doesn't make it a valid opinion.
