What's on the Line for Game 4 of Celtics-Hawks

Celtics17 presents the following opinion by the artist sometimes known as kaykaykay: If the Celtics don't win Game 4, I don't see them winning the title this year. You got to have mental toughness in the playoffs. If they can't beat the worst team in the playoffs (record-wise for both conferences) on the road, then what are their chances against the likes of the Cavs (who just won their game 4 on the road) or the Magic (ditto) or Pistons in later rounds? The pressure is just going to build with each round. At some point you got to put up or shut up. In years prior, the Big Trio (especially Paul Pierce) have complained they never had any help in the past which is why they haven't won. Well they have no excuses now. Hit the shots when it matters most.
