The most recent Hawks victory might have been their most important -- Saturday's win over Orlando put Atlanta 11/2 games up in the race for the final playoff spot in the Eastern Conference.
That's why Joe Johnson 's performance was so impressive.
The seventh-year guard, in his third season with the Hawks, played 45 minutes and scored a game-high 34 points.
Johnson shot 12-for-20 from the field, including 3-for-5 from 3-point range. He made all seven of his free-throw attempts.
Point guard Mike Bibby led Atlanta with eight assists. Johnson added seven assists to go along with five rebounds and three steals.
Johnson stepping up to lead the Hawks is nothing new. He leads the team in scoring, averaging 21.6 points per game.
