I think after the Sami Hyypia experience some people looked at Potter's CV and thought history might repeat itself.
Not from his CV, but I did wonder a bit at some of GP's team selections and playing people in strange positions, especially in some of those dark days last year before we started winning a few, if there wasn't a bit of the Hyypia about him - the difference being that GP wasn't trying to get his inventive ideas to work with Forster-Kaskey and Gary Gardner in midfield and Fenelon ad O'Gravy spearheading the attack! And I still wonder a bit!!
(and no, I'm not a Potter-outer, and I think we're heading in the right direction).
