nothing is wrong with the Suns, they are just coming back to reality. Most every team has a hot streak during the season, theirs was at the start.
I know what's wrong with them. It's called they were overachieving. Plain and simple. They don't have enough talent on that roster to keep up that kind of play for long. They could also help themselves by at least trying on the defensive end. I don't see how that could hurt your cause.
