TR, I agree that we should look for a new coaching staff next season. Earlier in the season I had hoped that there would be enough growth in this team to maintain a good deal of continuity, but I'm just not seeing it. If I were ownership, I wouldn't be giving Ninnis any messages until the season finishes though. If you do that, there is no incentive for the coaching staff to do their best for the remaining games and its not fair on Sixers fans or the league for the team to just mail it in.
As to who you bring in to coach, that is a tough question. Isaac has pointed out that some of the available Aussie coaches have their flaws too. Goorjian would be worth considering, but I suspect he will ask too much.
I just wonder if we need to repeat history? Bring in an ambitious young American coach with no preconceptions about/ connections to, any of the players around the club? Someone who will clean house, handpick new talent and drill it effectively for a couple of seasons. Someone who will create a new culture around the club that has basically been moribund for the best part of the last decade.
Also, just wondering why you think Ng and Hill can't coexist together? I agree there is a problem at the moment, because neither has proven they can consistently win their position as a starter. But I think if we could get a coaching staff that would DEVELOP both players, they could work together very well - Hill at SF and Ng at SG. Ng is your classic SG and Hill can shoot from range and slash quite effectively/ create his own shot when he has some confidence (which I have seen precious little of this season).
With the season now essentially shot, I really hope Ng and Hill both get a lot more court time. The Sixers HAVE to get enough information to decide once and for all if one or both or neither has a future as a starter. Import choices can then be made next season accordingly and the club will know what Aussie talent needs to be pursued as well. Not saying any of these guys could be had, but for example, do we pursue a Liam Rush, or a Chris Goulding, or a Damian Martin?
