New York Knicks - Philadelphia 76ers Basketball prediction

Early pick, as odds will drop. Opening game of Christmas Day. 
Knicks very solid at home this season 15-5 and even better record when Porzingis is on court.
76ers only 7-9 away and Embiid (back) will be game-time decision and Redick (hamstring) is very questionable to play. 
Correct line estimated Knicks about -4.5.
