I guess he only quoted Broon as he knew he would get a reaction and, subsequently, calls into the show.
From what I heard, Broon was the only one out of all the managers that he quoted that is currently in a job in Scotland, where his show gets aired (talked about MacPherson, Mowbry, Calderwood, etc).
I'm pretty sure he would have been pushing the Broon thing cos clearly this would create more noise from 'Well fans / listeners and ultimately result in more headlines for this prick than talking about some of the others where no-one would object (apart from the Hibees fans...).
The fact there is a post on here would suggest he done his job pretty well then....
Oh, and did I mention he's a prick....?
