No, it has nothing to do with the staff around him. It has to do with the fact both Stevenson and J.J. Taylor each fumbled and ended up in the doghouse. Obviously, when they made the decision on Michel, they hadn't planned on that happening and both of those players briefly fell out of favor. And obviously, they also never expected White - who has been consistently healthy - to go down with a season-ending injury. Bolden is reliable and they trust him, that's why he's in there right now. Even if some of us aren't thrilled about it.
I love you - but you need to stop looking for conspiracies where there isn't one to be had for the sake of feeding your narrative. Again, I know how you feel and that's OK - but mentioning it all the time and looking for additional things that aren't there isn't going to help. The best you can hope for is that someone else thinks he's great and hires him because he isn't getting fired anytime soon.
