In their two losses to Atlanta and Indiana, the Celtics  have been jumping out to quick leads but unable to put away teams in the fourth quarter.
That’s a trait they perfected in 2008. And in three blowout wins against Utah, Charlotte and Philadelphia, it wasn’t even an issue as they built leads of over 20 points in each case, turning the final 12 minutes in each case into prime time for the bench.
But against Atlanta, they were outscored 25-16 in the fourth and lost 97-86. In Indianapolis the next night, they were outscored, 61-43, by the younger, fresher Pacers, losing 113-104. The Celtics have led in the fourth quarter in each of their three losses entering Wednesday.
“I’m concerned about bad finishes than slow starts, honestly,” Rivers said before Wednesday’s contest . “I think all three of the games, we’ve had a lead in the fourth quarter. I said it [Tuesday], I don’t think we’re a 48-minute team yet.”
On Wednesday, the Celtics took a 49-48 lead to the locker room, somewhat deflated by the waving off of Kevin Garnett’s 3/4-court heave that hit nothing but net.
But the real question remains – Can the Celtics finish?
Stay tuned now and for the rest of the season.
