I have a feeling he will be an assistant coach UNLESS another club offers him a head coach role.
PS if he ends up with our top job only worries I have with him is:-
1. Defence
2. 2nd halves
3. Would he still perform if there is pressure of being our coach on him.
I love the bloke but let's be honest, he loves the job because there is no pressure on him now as the interim coach.
Defence is a big one, and I'd add to your list our continuing inability to score tries from within 20m of the line. Apparently we still rank 16th for this, which has to change if we are any chance of finals footy.
Fact is Potsy has done the best that can be done to get a quick change in results, simplify, focus the game plan on strengths and eyes up footy. Make sure the boys are having fun. These things have achieved the main thing that was needed at this stage, a turn around in confidence. Our systems as they stand however are not sophisticated enough to break other teams down in either attack or defence, instead we are relying on the mental factor of scoring tries from anywhere with unpredictable play and a bit of luck. It sure is fun to watch, I don't mind it at all, but we are unlikely to get deep into the finals without some solid systems that work well for us.
