Has John Wall hit his ceiling?

John Wall posted decent numbers in his first two NBA seasons. But how good can he be? Geoff Burke/US Presswire

One of the most intriguing young players in the league returned to action last week. John Wall and his blazing, high-wire act are back from a knee injury and, finally, there's a spark of life in the Washington Wizards' franchise.

Wall, a third-year point guard, is unquestionably one of the most exciting players in the world. Liable to dunk on an entire team at any time, Wall is must-see TV.

But that's about all we know about the 6-foot-4 lightning bolt. Two up-and-down, at-times-dazzling, at-times-exasperating seasons have left us without answers as to how good Wall will eventually be.

Sometimes that's how it is; no one would've predicted greatness for John Stockton, Gary Payton, Steve Nash or Chauncey Billups after their first two seasons, so Wall's inconsistent play so far is not necessarily a definitive statement about what his future holds.

But other point guards, particularly recently, have defined themselves as future perennial All-Stars much quicker than Wall. I'm talking about guys like Chris Paul, Kyrie Irving and Derrick Rose.

Wall's numbers are fairly strong. He's averaged 16.3 points and 8.1 assists over his first two seasons, but he's also committed 3.8 turnovers a game while shooting about 41 percent from the floor. So what does it all mean? How good does Wall project to be?

To find out, we asked several NBA experts who are paid to assess talent, potential and productivity for their thoughts on Wall. Here's what two NBA team executives and two scouts think of the No. 1 pick of the 2010 draft.
