I think the new coach will make a big difference. Almost 100% of the posters here think the coach makes no difference, which I find very interesting. Especially after all the fire Keele posts I’ve read..
There are things that a new coach can do - put speedy players together, put someone who will screen the goalie on the PP, teach proper zone entries and exits, etc.
There are things that a new coach can't do - perform testicular surgery, turn a muffin into a laser, make JT as fast as Willy, etc.
(Well, the last is possible - just add 20 kilo weights to Willy's ankles.)
