Boston is 41-27 on the season, which is good for fifth place in the Eastern Conference standings. It's been an up and down season for the C's, but they may have turned the corner during the road trip.

Smart has appeared in 67 games this season. The rugged defender is averaging 8.7 points, 2.9 rebounds and 4.0 assists per contest while shooting 41.9 percent from the field, 37.0 percent from beyond the arc and 79.5 percent from the free-throw line.

Rozier, meanwhile, is putting up 9.2 points, 4.0 rebounds and 3.0 assists per game. The scoring guard is shooting 38.9 percent from the floor, 35.7 percent from the 3-point line and 80.2 percent from the foul line.

The Celtics just defeated the Kings, but Boston has to come out and match Sacramento's energy. The Kings are fighting for their playoff lives right now and are a team which pushes the pace at every turn.
