Pete is not quite at the end of the line yet, but he's trending towards that direction, which is very alarming.
Whatever the reasons may be, they ALL fall to a single question at the end: is he contributing like an 11.6 mil per year player? As of now, the answer is a resounding "absolutely NOT."
We can speculate on reasons that led to his current slump, and he can say all the right things to the team, fans and media, but at the end, the question above is what he'll have to contend with.
I was in that place before, it feels like I put in the effort, and I tried to talk myself up but without tangible result, all of that is worthless.
Pete needs to get himself out of this quagmire - the walls are closing in, and the focal point of the magnifying glass will heat up very quickly.
