The unknown quantity in sports, especially when it comes to young basketball players, can be a very exciting thing. The idea of potential can often trump a tangible alternative. The situation with the Cleveland Cavaliers and their decision of whether or not to include Andrew Wiggins in a trade package to acquire Kevin Love is a great example of the struggle between the two ideologies.

The anticipation of getting to see a young player finally showcase his talent against the next level of competition can bring about an anxious feeling. If you were down on the player heading into the draft, are you going to look like a fool if they come out and look to be as talented as advertised? If you were high on the player, will you look like your "eye for talent" is blind if the player in question doesn't look like they belong on the court?

The first measuring stick for this type of confirmation of talent -- or lack thereof -- is the summer league season. Young players, unproven players, veterans looking for a second life, and unknowns flock to Orlando or Las Vegas or both, hoping to further their career in whatever way they can. But the energy that fills up those buildings the most comes from a rookie with high potential.

Being in the building, whether it's the size of a college arena or a high school gym, for the Las Vegas summer debuts of Dante Exum of the Utah Jazz and Nerlens Noel of the Philadelphia 76ers was electrifying. While Noel was limited to just two games, his impact in those games showed waiting for a year for his debut was worth the wait. Waiting for Exum to finally show us what he looks like against better basketball talent also started to justify the hype of this mysterious Australian point guard of this past year's basketball lore.

Judging summer league play can be tough because the process has so much more currency than the results. Good or bad, the stats dissipate into the ether almost instantly and certainly did with these two players. I couldn't tell you how many points Exum scored; I can tell you he held the collective attention of everybody in the arena as soon as he stepped onto the floor. As soon as he was bouncing the basketball against the hardwood, the presence and poise he displayed were dancing in the fantasies of fans and writers wondering how good he was going to be.
