Call it an educated guess. He was a 42 year old grown man working in a multicultural industry in 2014, an industry he'd been a part of for decades. All players & managers were involved or at least aware of Show Racism The Red Card types of displays, they've been happening for years. Having played alongside, coached and managed players from many different backgrounds and then come out with the stuff he did, combined with the half-hearted "apology" means he should have been binned. A course doesnt change that.
There's loads of excellent coaches out there, guys with better track records and none of the baggage, this is very poor by the SFA.
