HoopsHype has been maintaining a pretty impressive database of pre-draft workouts. Here's who the Rockets have been checking in on so far:

FIRST ROUND POSSIBILITIES

-Tennessee forward Tobias Harris
-UCLA forward Tyler Honeycutt (twice)
-Kansas forward Marcus Morris
-Kansas forward Markieff Morris
-Texas forward Tristan Thompson

SECOND ROUND (OR UNDRAFTED) POSSIBILITIES

-Richmond guard Kevin Anderson
-Clemson forward Jerai Grant
-Morehead St. guard Demonte Hunter
-Texas guard Corey Joseph
-Florida forward Chandler Parsons
-Georgia Tech guard Iman Shumpert
-Duke guard Nolan Smith
-San Diego St. forward Malcolm Thomas
-USC center Nikola Vucevic
-Georgetown guard Chris Wright

Obviously it's impossible to glean a whole lot of information from a list of workouts, but all of those first round possibilities are very consistent with the frontcourt help the Rockets have been interested in. Harris in particular has been a hot rumor for Houston, and has been mentioned in a number of mock drafts. It is rather interesting that they worked out Honeycutt twice, though it was on back-to-back days, because that would seem to be a pick that would buck the traditional "Chris Singleton or Harris" idea that seems to be floating around.

No new Rockets workouts are scheduled in their database, although of course that doesn't mean that more of them aren't coming.
