The plus side for Warrick at the 36ers would include his experience, and the fact that he wouldn't be looking for a whole lot of ball. My memory has him as a player who is happy to take what comes to him in the post in the way of catches around the basket, and put back rebounds, not being a focal point of the offence. He isn't a guy with much range, IIRC, which shouldn't be an issue on a team with the likes of DJ, Deng and Creek all able to play at 4.
If they are looking for a backup 4, it's a different question, and it may well be worth asking if the aforementioned experience might be interpreted as age, and that he might not gel as well with the younger core of the team (or they with him).
Personally, I doubt it will be Warrick, or any other NBL re-tread. If Adelaide is embarrassed by the whole debacle of the "he's injured"/"no, I'm not" affair, it might be a little while before they name a replacement, assuming they've got one in store.
