Imo this one man team thing is re-writing history a little. We also had the likes of Williamson scoring 14 from the wing, Quinn running riot, future England defender Maguire, Lowton, McDonald, that were all way above League One standard.
The issue was that we didn't have any other strikers capable of bagging even a few goals (only Cresswell). Even a remotely competent forward would have got us over the line that year. Instead we had the crock Hoskins and the woeful O'Halloran (the pair of which, between them, have scored less than thirty goals since that season...and one of them's been playing in Scotland).
Added to that, the Evans saga overshadowed what a huge blow it was to lose McDonald for the play-off final. He was huge for our creativity and ball retention.
The major failure that season was in not preparing for the eventuality that we'd had looming over us since the beginning of it. Any kind of back up would've had us alright. I don't think Wilder is that short-sighted and he won't be come the JTW.
