10* PLAYBOOK on Boston Celtics.

The Boston Celtics gave Atlanta a scare when they battled back from a 19-point deficit in Game 1 of this Eastern Conference Quarterfinals series. The Hawks won the game 102-101 in the end, but I like the Celtics chances of keeping it a close game and possibly record an upset tonight in Game 2.

Here are my keys to the game:

1. The Celtics' Team Spirit - Boston is likely to be without guard Avery Bradley due to a hamstring injury suffered in Saturday's game. "No change with Avery being out," guard Marcus Smart said on Monday's press conference. "Our little slogan is '(We're) one superstar.' It's us as a team. So this isn't anything new. If Avery was here or not, my responsibilities would be the same." Boston went 3-3 without Bradley this season, including a 106-93 victory over the Hawks on Nov. 13.

2. The Last Meeting - Atlanta held the Boston to 23.1 percent shooting in the first half of Game 1 but the C's came back strong and finished with a 36.3 shooting percentage from the field. They shot 31.4 percent from behind the arc while Atlanta made just 19.2 percent of their 3-point attempts, Boston should shoot better straight from the tip-off tonight with the nervy playoffs opener out of the way.

3. X-Factor - The Celtics were 22-13 ATS when revenging a loss vs. an opponent during the regular-season.
