Indeed. There's a difference between booing and some of the crap that fans say to managers. We've all heard it.
Funny, some Boston fans gave Heath an earful at Alfreton at the 1-1 a while back, he just laughed in their face and said "How many times have I stopped you lot getting promoted? Two? Three? I’ve lost count."
When you think back to a lot of our managers post PL, they've been a bit "nice". Elliott, Murray, Lee etc have all had to sit there and take dog's abuse from the stands, and one day - perhaps very soon - we'll get someone in who won't just sit there and take it.
