The only reason we have less promise than any other team has nothing to do with the roster. It's James Dolan.
His track record is impeccably awful. No other team has him. Surely the greatest disadvantage in pro sports.
That said, there's no particular reason a turn around can't happen very quickly, should Rose be a Rose. This ain't football. A couple of players turn a roster. Mitch, RJ, a draft hit, the right free agent, Woot there it is.
