Leads in the NBA are always precarious. That is at least what coach Steve Clifford will tell you.
Players in the NBA are too good and too talented to not have some run in them. The age-old NBA saying is every team has a run in them. No lead is ever truly safe.
Still, the odds of winning a game when there is a 20-point lead at any time is still pretty good. That is getting to blow out territory and to build a lead of that size takes some pretty strong basketball. Every team will have those games where they just absolutely kill it just like they will have those games where they struggle in the long slog of an 82-game season.
