Washington Wizards President Ernie Grunfeld misspoke last week after his team jumped up from eighth to third in the NBA draft lottery. Grunfeld said this is a “three-player draft.” Actually, there’s only one right guy for the Wizards: Otto Porter Jr.

Porter has everything it would take to fill the team’s long-term need at wing forward. He possesses the physical skills to play as fast as point guard John Wall and shooting guard Bradley Beal and the smarts to know when to slow down. The next time Porter relaxes on defense will be the first. When tough assignments are being handed out, Porter sprints to the front of the line. And many of the franchise’s starving-for-success fans enjoy rooting for players with local ties. The Georgetown all-American qualifies.

But of all the reasons Porter and the Wizards would be such a great fit, the most important is what Porter would provide both on and off the court: professionalism. For years under Grunfeld, key Wizards players displayed little of it. Grunfeld finally cleaned house, in part, to change the organization’s culture. Last season, the Wizards made a lot of progress along the road to becoming an organization that does things the right way. With Porter, the Wizards would get there sooner.

I can almost hear the doubters as I type this: “Some 19-year-old kid will help the Wizards act like grown-ups?” Yes. And that’s because Porter’s game isn’t the only area in which he’s advanced beyond his years.

You won’t find a more mature teenager with a great shooting touch, outstanding court vision and the desire to do whatever it takes to win. At Georgetown, Porter wasn’t a low-maintenance star. He was a no-maintenance star. That’s a rarity these days in the one-and-done and two-and-flew world of big-time college hoops.

Hoyas Coach John Thompson III never had to worry about Porter missing team meetings, slacking off in practice or making bad late-night decisions. For years, Wizards coaches could only dream about working with young players who are as talented and committed to improving as Porter. Having too many knuckleheads on the roster resulted in coaching changes. It’s hard to teach people who aren’t interested in learning. Porter is a sponge.

Now that Porter is headed to the NBA, I’m sure Thompson wouldn’t mind me sharing something he told me privately (and sorry in advance if you do, Coach). Thompson is convinced Porter will be a very good pro for a long time, as much for his steadiness as a person as everything he is capable of doing with a basketball in his hands. While at Georgetown, Thompson has developed some very good NBA players (any general manager would love to have Jeff Green, Roy Hibbert or Greg Monroe on his roster), and Porter is right there with the best of them.
