MIAMI — Late in the fourth quarter of the Celtics ‘ Game 1 loss to Miami, Kevin Garnett  delivered a foul on LeBron James  and then shared some of his famous internal monologue with James, who laughed back at him.
Asked later if he thought James and the Heat were “showboating,” Garnett responded, “A little bit. Little bit. It’s all good. They’re home, they’re comfortable. And when you’re comfortable, you do things like that. We’ve got to make sure we take them out of their comfort zone and fight a little harder.”
The comfort zone was something the Celtics talked about after the game in regards to James and Dwyane Wade , who combined to shoot 60 percent and score 54 points. Coach Doc Rivers  said his team allowed them to play “in extreme comfort,” tough words for a team that lives on its defensive pressure.
Rajon Rondo  said the C’s needed to “shrink the floor,” which is one of their main defensive principles. Someone asked if that meant being more physical and Rondo replied, “I mean, nothing dirty, but you know, they have to hit the deck, too.”
Two problems here. One, they can’t hit what they can’t catch, and two, who’s going to do it? This is one of the most mentally tough Celtics teams of recent years, but they don’t have an enforcer. It’s not their game. The issue for the Celtics isn’t hitting Miami, it’s stopping the Heat before they get there.
Regardless, expect this to be a huge thing for the next day and a half until Game 2 tips on Wednesday.
