We debuted our first 2013 Top 100 the day after the 2012 NBA draft. Now we're ready for our first big update of our Top 100. How can players improve their stocks during the offseason?

The truth is, there isn't an offseason anymore. College players serve as camp counselors at events like LeBron's Nike Skills Academy and the adidas Nations camp. At the end of the day, the camp counselors play full-court scrimmages against each other and sometimes against NBA players.

NBA scouts are in attendance and the impressions that these players make in the summer can have a huge effect on how they are ranked and evaluated throughout the course of the year.

Over the past few weeks I've spoken with a number of NBA scouts who were in attendance at these camps. Here's a look at a handful of guys who have helped or hurt their stock this summer.

The freshmen

Nerlens Noel, F/C, Kentucky Wildcats
Noel showed up at the adidas Nations camp last weekend and, by virtually every account, was a major disappointment. While longtime high school gurus knew that Noel was incredibly raw, NBA scouts got a pretty big taste of just how raw he was. Offensively, Noel struggled to do anything other than dunk the ball. Defensively he showed why he was a terrific shot-blocker, but did little else to impress.
