I am sure some of us are doing a "HA-HA" right now about this... and you can't blame us. Marshall did use Bama for his pay hike (and a smart move at that) so there is to be some butthurt from our fanbase.
According to what is published ol' Gregg seems to have a bit of a temper. Note these are allegations, but generally speaking where there's smoke there's fire so I am inclined to think there is some truth to this. Probably not 100%, but enough to make WSU dig a bit deeper.
