Celtics Battles Heat But Fell Short

Game 2 of the Eastern Conference Finals was an epic. First quarter was for Boston leading as much as 15 points. But the Heat bounced back in the second half, the fourth quarter battle was a thrill..but in the end the game fell back to square one. The Celtics forced an OT after tying at 99 at the end of the fourth.
As the game was extended, the Heat controlled the tempo. Dwane Wade and Lebron James powered the heat during overtime but their counter part Rajon Rondo showed heart until the last second of the game.
Rondo shot a two consecutive three's making it a 3 points lead at 2.2 secs left during OT.
Rondo who has 44 points, and played full minutes in Game 2 can't help but look at the time fading. Great performance indeed for Rondo but couldn't help his team to tie the series.
Are we witnessing a sweep by the Heat?..or the Celtics will still emerge victorious?..
or a championship series between HEAT and SPURS is in the making?
