What's happened in Vegas?

The opening weekend of the NBA Las Vegas Summer League is in the books, and what did we learn?

Greg Oden and Kevin Durant are going to need time to get adjusted to the pro game.

Yi Jianlian is almost certainly going to play in Milwaukee this season.

Marco Belinelli and Javaris Crittenton could be this year's draft steals.

And if you happen to be in Sin City in July, wear light clothes and keep lots of bottled water handy.

OK, so maybe we're getting ahead of ourselves on all but the last one. After all, we're basing these observations on only one or two games at the start of a 10-day tournament that will feature 20 NBA teams composed mostly of rookies and free agents.

But with 100-degree temperatures turning Vegas into a blast furnace, it's easy to suffer heat stroke and get carried away a little.

At the risk then of these observations turning into a mirage, here is a rundown of what occurred over Days 1-3 of the NBA's summer session in the desert.

You can tell a lot about a person by how he handles disappointment. Neither Oden nor Durant lived up to the hype in their pro debuts Friday night, but they both showed a positive attitude that should serve them well as they go through the requisite growing pains.

Oden, in particular, displayed a maturity beyond his 19 years. Though clearly disappointed with his performance -- in which he committed 10 fouls in 20 minutes -- he refused to blame the refs or the sinus infection that had been bothering him for a few days. He even found room for a little humor, joking with reporters about the summer's league 10-foul limit by saying that he usually fouls out after only five.
