Nate McMillan isn't an elite coach. But he's a solid pro and he has the Hawks playing and looking far more respectable than they did under Lloyd Pierce. Atlanta has surrendered an average of just 104.5 points in its last four games. The Hawks have moved into the top 10 in defensive field goal percentage and rank No. 2 in defensive 3-point percentage. 
Houston is last in 3-point shooting percentage. So don't expect the Rockets to hit many 3-pointers. Houston is decimated with injuries, averaging only 99.8 points a game during their last six games. The Cavaliers are the lowest-scoring team in the NBA and they average 103.3 points. 
Houston may get Danuel House Jr. back, but Christian Wood, John Wall and Eric Gordon are not expected to play leaving just Victor Oladipo as the Rockets' lone respectable scoring threat. 
Note, too, that 80 percent of the Rockets' home games this season have gone Under at 12-3-1.
