I dont think anyone personally hates him. Its more of how the program had fallen and putting the blame on him and who else can you blame with him being the HC? The man is/was a legend, thats not gonna change.
Sure it slipped a little but Fulmer was a household name and people would come from all over to play for him. I think looking back over the last 10 years should show we took him for granted and we did him wrong. He was 1 year removed from playing in the SECCG and we had a 10 win season. For various reasons we havent had one since.
