I honestly agree with you, that has to be part of it.
As soon as anyone cites the last eighteen months of football as a reason Heath's rubbish, any sympathy I had for them and their argument flies away. We were promoted last season, and you literally can't do better than that. There are plenty of clubs that sink into a league where their support is amongst the largest, who stay there for a while longer than a season.
And Heath hasn't done owt at this level... because he's been at this level for less than five months, under a club with no significant financial clout. That's all. All of which have been characterised by some very special people who've hounded him non-stop. Few managers see any success while there's been a faction who victimise them and all their efforts non-stop. To Heath's credit he's one of the better few. These people have said it all along, and whenever bad form comes along they're delighted because it means the majority are apparently waking up to what they said all along. It's the same as starting to complain about the cold in April, and waking up this morning going "See? Snow! I was right all along!"
What we do know is that with full backing, Heath has taken his former club into this league to be one of the all-time smallest outfits to have featured at this level. It's that managerial ambition that the board would've seen in him. Now let's imagine what he can do with us when given time and backing (it'd be a first), so we can pull through this pedestrian example of bad form, watch the injury crisis blow over and see what's learnt. Few middling Conference sides have seen success by starting over at the slightest shock, otherwise Southport would be in the football league by now. Slow transitions and building on what you've got work a charm, as Macclesfield, Aldershot, Sutton and Dover are currently showing.
