It appears to be infinitely more likely at this stage that he did indeed make that call.
On one hand we have Bruce telling us that he asked for another coach, someone to help with the transition they were trying to make, and Jones was his first choice.
On the other hand the only dissenting voices to this statement from Bruce, is our fans who want to hate Bruce, and so have created a load of alternative reasons why Jones was appointed.
We all know in football, you don't always find out the true story. At this stage however, given the evidence at hand, our fans are looking like a bunch of prima donna idiots looking for something to complain about.
