More than three weeks have passed since training camps opened in the NBA, and along the way, we have been treated to something we didn't get last year—actual stretches of exhibition games. The games won't start counting for another week, and it is hard to put too much stock in what happens at this time of year. Still, there have been some players worth watching early on, players who have given some very positive glimpses for the upcoming year:

Anthony Davis, Hornets. Davis was the No. 1 overall pick, and he spent the summer with the U.S. Olympic team, so it should be no surprise he has come into October ready to play. But what's been most impressive about his preseason is the quickness with which he has latched onto Monty Williams' coaching.

Coming into the year, the thinking was that Davis would be an impact player defensively from the beginning and that his offense would take some time to develop. But Williams has pushed Davis to produce offensively throughout the preseason, trying to build Davis' confidence in his midrange jumper, going so far as to play Davis at small forward at times.

Davis still needs work—he is shooting 43.5 percent—but Williams has been encouraged by the results, with Davis averaging 13.4 points and 10.0 rebounds.
