The concern will be that we will live to regret employing SM with no guarantee the current owners will find themselves in such a great position again that deep into a season.
Put it this way.... Who thought 12th placed Crawley Town were a better team than Notts at the time LW left? They are now playing in tier 3. With Crawley in mind, Notts definitely could have gone up last season had they replaced LW with somebody half decent.
It's all well and good if SM ultimately delivers but I still think he'll turn out to be another Burchnall type of manager, doing enough to stay in the job but not actually getting Notts over the line. At this level, that is going to be no less frustrating than it was being stuck in tier 5 before LW came along.
