If you imagine a big computer game style energy bar that a manager has at a club in relation to fan backing, you get some managers that have that knack of extending it and some that will just instantly drain it.
Pearson had the knack of losing a game or two, being stubborn and even calling out the fans, but he had this way of managing his bar to not move far.
Rodgers I always thought, even when things were going well, that his personality and style would mean his bar would empty very quickly when things got tough, which it did.
All the frauds we've had recently that have come in and played the same horrible players and style to the previous managers - your bar instantly drained.
I worry for Martin if things go wrong and he's there doubling down post match refusing to take ownership for things... His bar will be going into some unknown negative territory we've never witnessed before... quickly!
