Robert Covington is the only player on the Rockets roster who has yet to play for Houston.
15. Robert Covington
Covington signed on with Houston as an undrafted free agent to play in the summer league. After a promising performance in Orlando, he earned himself the final spot on the Rockets' roster.
So far this season, Covington has been taking advantage of a wonderful opportunity in the D-League with the Rio Grande Valley Vipers. He is averaging 19.9 points and 9.3 rebounds per game, with an incredible +/- rating of over 22. However, the Rockets signed Covington because of his three-point shooting, but he is only connecting on 31.7 percent of his attempts from behind the arc.
If Covington can get that three-point percentage up and continue to play efficiently, he will get the call to come play for Houston before the year is over.
14. Isaiah Canaan
Canaan was playing extremely well in the valley before getting called up to the big leagues after Patrick Beverley fractured his right hand. As of late, Canaan has been riding the pine for the Rockets, appearing in just one game during a blowout loss against the Oklahoma City Thunder.
His 21.7 points and 9.2 assists per game with Rio Grande were enough to get him recognized by management. When Beverley returns, Canaan will most likely return to the valley because of the Rockets' tremendous depth at point guard.
With Beverley, Jeremy Lin and Aaron Brooks all ahead of Canaan on the depth chart, he will just have to wait for his opportunity to play in the NBA, but he is definitely capable.
13. Ronnie Brewer
This has been a disappointing season for Ronnie Brewer, most likely because he's a poor fit in Houston's system. Brewer is a defensive specialist, which the Rockets really need, but he can't score worth a lick. When he gets the ball on offense, he completely disrupts the Rockets' offensive rhythm, making him a liability.
His lack of any offensive game is why he has only appeared in 16 games this year and is averaging a pitiful 0.3 points in those appearances. He's a 25.6 percent career three-point shooter, and the Rockets attempt the most threes per game in the NBA.
Brewer may not even be on the team by the end of the year, but he gets the nod ahead of the two D-Leaguers on the power ranks simply because he has been on the roster all season long.
12. Donatas Motiejunas
Daryl Morey and Houston fans were hoping that Motiejunas would have more of an impact after coming over from the Polish League. His game has not exactly translated to the NBA as smoothly as Morey thought it would, and as a result, his minutes have taken a huge hit.
D-Mo has shown some flashes of low-post potential but has not played consistently enough to get a foothold in the rotation. He has seen the floor in only 17 games all year and is averaging 2.7 points and 1.5 boards.
With Omer Asik and Greg Smith struggling with injuries, Motiejunas was still sent down to the D-League. According to Adrian Wojnarowski of Yahoo! Sports, Motiejunas wants to be traded. He wants more playing time, plain and simple.
11. Greg Smith
Injuries have plagued Greg Smith all season long and have kept him on the sideline. He has only played in nine games this year, and the Rockets need him to get healthy with all of their big-man issues.
With Asik still out, Smith is the primary backup at center for Dwight Howard. Smith can clog up the middle and run the floor well for a big man. He just needs to get that knee to cooperate.
