In response to Gabe Vincent's warning, Charles Barkley taunts "not gonna lay down." 

In a postgame interview with NBA on TNT, Miami Heat player Gabe Vincent attempted to gift their opponents flowers ...

...after the Miami Heat thrashed the Boston Celtics in Game 3 of the Eastern Conference Finals. 

Vincent said he thought Boston was a well-coached club that wouldn't go down easily.

Charles Barkley disagreed, taking potshots at the No. 2 seed in the East. 

Some league observers predicted that the Celtics will fight hard ...

...on Sunday to avoid falling behind 3-0 going into Game 4 on the road. 

The Heat, meanwhile, didn't even give their rivals a chance, 

pulling away from Boston in the opening period to win handily.
