Possibly. The MK Dons situation was a bit of a farce. He got something like 15 or 16 games there, which is mental. His time at Bradford and over the next few years will be a better indicator of if he can get back on track.
Although in saying that, I don't really think how many times a manager has been sacked can be used as a barometer of his abilities, as mental as that sounds.
What Alexander had that Kettlewell doesn't is a track record of some form of success. I think that's why I had more confidence in Alexander than I do Kettlewell.
