The 20-year old rookie is no doubt trying to change his mind.

In his Vegas Summer League debut, the Rockets rookie exploded for 40 points and dished out the game-winning assist as the Rockets topped Robin Lopez and the Phoenix Suns 100-97 Monday night.

Mike Harris added 21 points and 13 boards while Maarty Leunen added 16, including the game-deciding bucket.

Greene was the star in this one though, and was efficient to boot, hitting 12-20 shots, including 5-10 from beyond the arc. He had 19 points in the first quarter alone.

"Once I got to 36, Phoenix started keying in on me a lot more so I started to look for my teammates to get them going," said Greene. "I got Aaron going, and Maarty, and Mike Harris and we got the win."

The 6-foot-9 forward, who signed his Rockets deal earlier in the day, showed a quick release and looked confident putting the ball up. While he's certainly no Tracy McGrady, he did look somewhat T-Mac-like in the way he launched shots -- long, lean and smooth with his jumper.

It's just summer league, where even Steve Novak can look unstoppable, and it was obvious that he had a green light that he won't see on the real squad. Defense also was not a real big item in this one.

Still, it's a great start for Greene -- if he keeps this up, it could be real hard to justify playing Luther Head and/or Steve Novak ahead of him.

Here are a couple of highlights:
