On Bohs, it's more that any manager will struggle to emulate the herculean effort Fenlon managed in the circumstances, so they needed to make a bigger-name appointment, rather than any sleight on O'Callaghan. Also, I thought the money problems might result in a player exodus, which thankfully, hasn't happened yet, so have adjusted them to 7th now.
As for Leeson, when Galway went bust in April, he resigned and GUST took executive control until the end of the season. Their breakaway caused the final collapse, and the most likely current scenario is a hybrid Galway & Mervue FC.
