No? Where did this Patterson as a SF nonsense come from? He's strictly a PF. In college he played center before Cousins came, then moved to a perimeter PF type player. There is no way he can play SF.
This isn't the NFL, Ish going to the Vipers will be because they no longer need him to backup the point in case of injury. Both Patterson and Smith are on the roster and could technically ride the pine if the team wanted. They will most likely take a look at Patterson and unless he is suddenly a more impact player, ship both to the Vipers once Brooks is back and the team hits the road for another extended trip.
Actually Adelman practiced him a lot at sf in the preseason. I got the impression that he didn't impress that much there and when moved over to his natural position he began to play better. So probably right sf is not his position but Adelman at least thought it was a possibility.
