it will be hard for the celtics, but not at all impossible.
in the playoffs the hawks beat the celtics three times in atlanta, but the score were....
Atl Bos
102 93
97 92
103 100
an average winning margin of 6.1 points. not overwhelming and i thought the last two games could have gone to the celtics.
when boston won, they did so by an average of around 20+ points. in three of the victories the celtics won by 22 or more points.
if both teams play their best games, boston wins. but boston does have to play their best game to beat atlanta there.
