The explosion of 3-point attempts throughout the NBA caused a sea change in how teams score the ball, scout players and game plan.
Some teams baked the 3-point revolution into building their own rosters. The result is several heavy-hitting teams who can use their considerable talent from beyond the arc to fight their way back into contests. Just ask the typical opponents of the full-strength Golden State Warriors, the Los Angeles powerhouses in the Los Angeles Lakers and LA Clippers or the Milwaukee Bucks.
So, they say in the modern NBA, no lead is safe.
