Unlike the sometimes threatening objects radar is designed to locate (like missiles and submarines), most of the NBA's free agents aren't actually trying to evade it. In fact, it's safe to say most who've made it this far without finding a deal could actually use a little more radar aimed their way.
That's a tough sell in many of these cases. Some of the best free agents left on the market spent their 2012-13 seasons with the likes of the Charlotte Bobcats, Orlando Magic, Cleveland Cavaliers, Portland Trail Blazers, Atlanta Hawks and Utah Jazz. It's not about these teams being bad; it's about no one noticing them in the first place.
And so it is some of their free agents have gone similarly unnoticed, dodging radar like torpedoes headed straight for the Development League. It's too soon to declare them all bound for the D-League, of course. We know that won't be the case for Mo Williams, who the radar simply forgot about. Nor will we see veterans like Leandro Barbosa or Beno Udrih go without one last NBA role-play run.
Unless they can make a lot more money overseas, anyway.
It's also worth noting that even if these guys have flown under our radar for the most part, that doesn't mean front offices around the league haven't been watching. There are still roster spots to be filled and still more openings may emerge as prospects get demoted or injuries warrant changes of plans.
And as we'll see, some of these free agents are already close to joining the ranks of the NBA's employed.
