How many rookies did the Rockets draw in 2009?

The rocket finally got something in the second draft. They first got the Wizards' No.32 draft pick and rookie Jeremy Taylor for $2.5 million, and then traded the Nuggets' No.34 rookie Sergio Luer. The rocket did not stop buying. After that, they got the No.44 rookie Chase Badinger and some cash in the next two draft picks through an agreement with the Pistons, so the Rockets recruited three rookies in the second round.
