Few downsides (other than for Marty):
- club gives him every chance to show ability; if they cut him after this, they will know they tried something at least
- tests out the Stirling/Maher/Davis influence people always go on about on Hoops without throwing them into F/T coaching
- doesn't bankrupt the club, but shows some action
- might give players a sounding board if they have frustrations
- if Marty bails out of frustration, the pay-out is saved
For Marty, if it helps, that's good for him, as much as it might be a bit humiliating. (Press release at season's end, summarised: "Coaching is my thing and it's something I've done for many years. Coming in to the NBL, there were challenges I didn't expect to be so difficult and every week brought new adversity. I don't think I adjusted quickly enough and the results showed that. Bringing in fresh eyes and thoughts in Maher was a real key, I'm not embarrassed to say, and that's looking like an improved scenario for the team's results." Etc.)
If it fails, so be it. Same could happen with a completely new coach or with having changed nothing.
I would make it Stirling and Maher and leave it at that. Don't quite want coaching by committee in adding various others.
