What the hell just happened!!
18 total points for the Miami Heat starters. And the last time it happened was 1970. 
Overconfidence or underestimating the Boston Celtics because they stole one game in their home? I bet Udonis Haslem is preparing his big talk again.
I know Jimmy Butler is exempted from the blame as he was hurting and could be mentally unprepared but the rest of the crew should do something about it.
Congratulations to the Celtics though, great defense.

Al Horford played the defense. Wow. 4 Blocks. Stopping the Miami Heat to get the 3rd win and a chance to advance quickly in the Finals by ending it in their homecourt. This is a possible Game 7 from now on. I had been looking down at the Celtics team after I saw them defeated even with Marcus Smart around and Al Horford. Now I am admiring their will to win.
But Game 5 will be the crucial moment for them. If ever the Miami Heat shows weakness (Butler injury) then they should take advantage of it for a chance to end it at home. 

If you watched the final minutes of the game, Haslem really is talking to his teammates especially to Lowry.
Lowry has a hamstring injury, Butler and Herro are injured, and you can't rely on Strus and Tucker to put some big points as well. I agree with what you said though that the Heat are disappointing tonight.

I believe that the Heat will bounce back in Game 5 and if Herro will still be out on their next game, they must utilize Robinson more at least in this series because he really is a good 3 point-shooter. The only problem with him is his defense, but his offense can cover it up (I think).

The Celtics are performing well this year that they didn't have consecutive losses in the regular season as well as the playoffs. They know how to adjust after a loss. The Celtics must win this series because the Warriors are waiting for them .

Well the Miami Heat vs Boston Celtics series certainly just got very interesting. I was shocked to see how poorly the Heat starters played. Also have to wonder if Jimmy Butler will play fully healthy at all during the rest of this playoffs. I have to think he wasn’t feeling at his best last night.  Just insane him, Lowry and two other starters all being held under 10 points.

Indeed, the bounce back really shows how Boston eagerness not to allow Miami to take a 2 game lead from this series.

Tatum's adjustment gives them that huge edge to win the game at home. The series is now going
to the best of 3, Miami needs to make a good adjustment moving back at home.

They need to protect that home court advantage defense and chemistries in moving the ball
to execute proper offense.

For me, this was really inevitable because most of the Miami Heat key players were injured even before the game earlier like Lowry and Butler, also Herro wasn't there to at least help the team chase the Celtic's lead but was also suffering from an injury. Jimmy Butler should have just rested because they quite know already that their chances on winning game earlier was really low because the almost all the key players on the Celtics were present. Now, they just made their situation even worse as the Celtics will be always watching for them to have an advantage.

Yeah, the upcoming matches of the Heat vs. Celtics series are likely to be very intense. So I wouldn't be surprised if the winner of the Eastern Conference finals is determined only in the 7th match of this series. As for the Western Conference, there is no doubt that the Warriors will win the WCF. Although it would be expected if the Warriors let the Mavs win tonight, and then they win the Western Conference title in game 5 at the home arena.

^ Warriors forcing Luka to go right and trap him there has been effective in a few possessions but the Mavs three is dropping. I didn't check the stats in the third quarter but I think they scored more beyond the arc than in the paint or perimeter. Trailing by 29 points, I think Kerr will rest his starting players in the fourth quarter. It's not a bad decision to avoid any injuries in the fourth and finish the series at home.

Unrelated to basketball but it's nice if the Mavs get the W here as a tribute to the victims of the Texas shooting.

WTF is wrong with Mavericks always on 2nd hald. They have 19points advantage with just 5 minutes remaining while there full force team is totally dominated by the GSW bench and down the lead to 8 points with 3 mins remaining. I don't bet on any of this team but GSW seems like giving away this game but Mavs don't want to take it. Kuminga has an impressive 3 points shot to cut the lead on to singe digit. I hope Mavs can get this match for a better next game match.

Mavericks pulled off 1 win, I think the series ends in game 5. GSW will close it out at home. Luka is a good player, but he is a ball hog and needs a couple more years to mature.
