Kelly doesn't have trust with a lot of fans right now, and that's of his own doing.
In 2011 he went crazy on TJ Jones.
Post USC in 2011 he gave that speech about my guys versus the guys who were here.
Post 2012 he flirted with the NFL.
In 2014 he placed a lot of blame on Golson.
He defended his terrible 2 point decision against Northwestern.
In 2015 he made another awful two point decision against Clemson and defended that as the right thing to do.
And then last year over and over again.
He's made mistakes in games that he's never owned up to, so people don't give a shit what he says after 4-8 when he's trying to save his job.
Personally, I don't think he's really any different than most coaches. But, he hasn't won enough, so people will take his negatives and latch onto them.
