Now that the trade deadline has passed, I think this question can be asked. The Rockets now only have rookie power forwards, and the 'play Delfino as our starting PF' era will probably come to an end soon, especially once he has to guard a Blake Griffin or Dirk or Aldridge or David Lee.
Donatas Motiejuans - He increases the size and length of our starting front court, while maintaining a 3 point option. However, he commits silly fouls and has shown a propensity to force shots around the rim. This could be because of the lack of playing time leading to a feeling a desperation to prove he can make an impact, or it could be just dumb rookie mistakes. He also has shown a bit of weakness defensively.
Terrence Jones - He has struggled even more than Motiejunas to get off the bench. He has lots of physical tools, can put the ball on the floor and shoot it from a decent range of places on the court (although he doesn't have the 3 point shot in his arsenal yet), but lacks size (a problem we also had with Patterson and Morris) and is incredibly inconsistent.
Thomas Robinson - He has a good motor, but tends to get his shot blocked a lot, doesn't know the offense, and like all rookie big men, commits silly fouls. He, however, is a very talented rebounder, and plays above the rim. He would add an athletic presence that currently is non-existent in our front court rotation.
Personally, I see Motiejunas' minutes going up from here, and in perhaps 10 games, he will get the starting nod. The rockets have gotten by pretty fine thus far without a starting PF who rebounds the ball really well, so Robinson gaining an advantage on that front seems a bit far-fetched. I think Robinson will be the 2nd big off the bench (along with Greg Smith), to give us scoring opportunities from offensive rebounds and attacking opposing bench big men. I think Terrence Jones will continue to remain out of the lineup, and shuttle between the team and the D-League.
