It's easier to have belief in someone telling you how they will win you football games directly than someone telling you how their are names in envelopes and that he already believes a few of you suck, or a saying in latin, or how he is his own mentor(while stealing management ideas from every other manager).
Rodgers comes across like he has attended to many management seminars held by management 'guru' types. He talks a lot without saying anything at all. I can imagine the entire team cringing throughout every speech he gives to the team. Rather than instructing the defence how to improve and deal with different situations just telling them if they believe and try hard they'll improve.
All managers say some dumb stuff in the press, because humans tend to say dumb stuff all the time, but almost everything out of Rodgers comes across as cringe worthy and stupid.
