Wizards point guard John Wall has missed all of this season to date with a left patella knee injury. No date has been set for his return, but Wall has said he is eyeing a return in January. For all we know, it could be the last week of January. This is Wall's third year in the NBA. While he certainly does fill the box score, is it worth it to the Wizards to keep him or trade him?For his career, Wall is averaging 16.3 points per 8.2 assists per contest. For a point guard not named Russell Westbrook, those are pretty solid numbers. But Wall is only shooting 41.6% from the floor. His three-point accuracy is horribly bad. Last season, he didn't even attempt one 3-pointer per game, and made only 7% of those. His rookie year, he made only 29.6%. My point is that for Wall to keep that 16 point average, he's going to have to jack a lot of shots, and he's going to miss a lot more than he makes. Next year is Wall's final guaranteed year under his current contract. The Wizards have a club option for $9.7 million for 2014-15. His salary for this year is $5.9 million and he's scheduled to make $7.5 million next year.With all of that in mind, something else may determine if the Wizards front office decidese to deal Wall.Wall's first year in the league, 2010-11, the Wizards finished last in the Southeast, and had the third worst record in the Eastern Conference. For the 2011-12 strike-shortened season, the Wizards finished ahead of the record-setting Bobcats, but that was the only team they finished ahead of in the entire Association. The evidence suggests that even with Wall on the team, he isn't making a big enough impact on the court to improve the team. Of course, if you've followed the Wizards for any amount of time, you'll know they're the Clippers of the East, complete with cheapskate owners Abe and Irene Pollin.All of that being said, either the Wizards need to spend to surround Wall with some players to actually improve the team, or they need to trade him and get something of value for him while he still has some.
