With respect, neither are for me to answer. Looking on the search function on here, Gary Rowett was barely mentioned prior to being appointed other than alongside the usual speculative posts with Eustace and Mous that appeared every 6 months.
I don't care for football generally if I'm honest. I don't know much about established managers at this level let alone those who are up and coming or those going under the radar. So I'm the least qualified of posters to put names in the pot (although Kip probably runs me close!!)
As for those above, that's a much bigger issue. I said in the summer that Waldron was not immune from criticism, and at this level you either need to out spend others or out smart them to get ahead. We won't out spend many so we need to be smarter, and thats hard with someone so inexperienced in his role and at this level. But equally, most of our summer signings have looked decent at times, and a change of manager or a decent run of games could yet show that the recruitment was much better than some are saying.
As for Williams and Ferguson, both are Ericks men, and I can't see either going anywhere. As frustrating as that may be, I'm not sure that its a battle any of us will win.
