After vanquishing the Oklahoma City Thunder for the 2012 NBA championship, the Miami Heat went out and became even stronger this summer.
The addition of Ray Allen, the most prolific three-point shooter in league history, gives the Heat the reliable sharpshooting option they lacked for most of last season. The thought of LeBron James or Dwyane Wade driving and dishing to a wide-open Allen should be terrifying 29 other fan bases.
There's no guarantee that 33-year-old Rashard Lewis has much left to offer besides three-point shooting (with 38.8 percent career average) and the ability to fit into Miami's positional revolution.
With their Big Three still intact, though, do the Heat need much more from him? Doubtful.
Assuming Miami hasn't suddenly replaced the original Dream Team as the most unbeatable team in basketball history, they'll still have at least a few challengers to their throne next season.
These are the five teams most likely to topple Miami in their quest to repeat.
