As a dangerous January schedule looms, Boston hasn't been playing up to its standard recently, falling 4 games out of first in the East.

The 76ers saw the game out and took the Christmas Day battle, 118-114. Boston falls in consecutive games for the first time this season after being the only team in the NBA without two straight Ls. Jayson Tatum ended with a double-double to the tune of 32 points and 15 rebounds.

But Maxey zipped past Pritchard and found a clear lane to the basket, where he put in an off-balance layup just before time expired. The play all but finished off the Celtics in this 118-114 loss, and it was an example of the uncharacteristic missteps that doomed them.
