There are a lot of people, even some here, who laugh off the idea of hiring character guys. I'm not one of them. But the notion that every Spur player in the last 20 years has been a choirboy is pretty laughable. The way the game is being played now, you have to have a certain amount of athleticism and versatility. Your article mentions that it's not enough to just be big. Bryn Forbes is proof that it's not enough to just be a shooter.
So what is a "character guy" exactly? The team should rule out guys whose off-court baggage will be an on-court distraction. But we all watched Pop put Bertans in the long-term doghouse for coming to a teammate's defense, and getting ejected. People tried to deny it, but that's what happened. But then Pop turns around and calls his team "soft" at least once or twice a year. Tony Parker's off-court drama sure as wasn't the kind of thing I would put under the "character" heading. I think it wound up being a distraction, too. Pop didn't give any signs of being less than supportive.
Find guys who are reasonably athletic and versatile, and who are coachable and willing to work hard. Don't penalize the ones who have their teammates' backs. And if your system really lives up to the legend, the "character" guys should be a good influence on the ones who aren't choirboys.
