The Rockets don't know where they'll be picking for sure yet, but it seems likely that they'll be stuck at No. 14 overall. Likely as in "99.5% chance," which are the odds that Houston would need to defy to win the lottery. No worries though, as Houston has made a living under Daryl Morey of finding talented players late in the lotto; say hi to Patrick Patterson.
While not many official mocks are being put out now, the guys at The Basketball Jones took their shot at it, and they have Kansas' Markieff Morris going to the Rockets at No. 14 overall:
14. Houston Rockets - Markieff Morris, ‘6'10" PF, Kansas
Between the Morris brothers, Markieff is the more aggressive one, especially on defense and when it comes to rebounding. He's limited offensively, but has steadily improved his perimeter shot. Where he'll make his mark with the Rockets will be on defense where he should be able to man-up against any post player and provide some help against other offensive players.
Either of the Morris twins would make a lot of sense for the Rockets, particularly if Houston thinks they have the bulk to slide inside. NBADraft.net has the Rockets taking Kawhi Leonard of San Diego State this week, and Draft Express has the Rockets landing Texas' Tristan Thompson, who might be a bit short and slender for an NBA power forward right now.
