My buddy (but a 9er fan) played HS ball for Holmgren at some Catholic school in SF. Yes, he was previously an alter boy and the jokes just get better and better.
(This conversation took place in our SB year).
My friend said Holmgren was "mean as hell" and "difficult to get along with". I asked him to elaborate, and he said Holmgren "got pissed and once grabbed (him) by the neck".
I asked what he was doing wrong to deserve such mistreatment and with a straight face he said: "me and a friend showed up for practice one day laughing our ass' off and rolling on Mescaline".
I sh*t you not.
