Clubs these days generally seem to prefer to give the extension and pay the contract out if it all goes wrong rather than endure the constant speculation when the club loses games in the final year of a coach’s contract. Not saying it’s the right call, but it seems to be the one most commonly made (Buckley last year aside).
The other fact that the club might consider is that Woosh couldn’t really have done much more in his first two years. Kept the club afloat and competitive in 16, made the finals in 17 with the returning players. I don’t know if he’s the man either (I suspect not), but to this point I would say his tenure has been a solid 8/10 considering the surrounding circumstances.
