Can anyone really stop the lights-out Cavs?

After quickly sending Atlanta home, Cleveland now appears to be the hottest team in the NBA Playoffs, which now includes these burning questions:

• Can the Blazers count on getting absurd Damian Lillard (and Al-Farouq Aminu) performances while Steph Curry inches closer to coming back from his knee injury?
• Is Kyle Lowry’s huge Game 3 a sign of things to come vs. the Heat?
• How much will Hassan Whiteside’s injury absence affect what the Heat can do on both sides of the court?
• What the hell is going on with San Antonio's fourth quarter offense?
• Can KD stay locked in (on offense and on Kawhi) for the Thunder as they attempt to take down the extremely efficient Spurs?
• What can Golden State do and who can they do it with to maximize their healthy talent and take advantage of some obvious Portland deficiencies?
• Why is the Cavs' new lineup of LeBron-Kyrie-Love-Smith-Frye so damn unstoppable?
