That screeching noise that's invaded your ear holes the last few days? Don't worry, that's just the sound of the NBA offseason grinding to a halt.

The NBA Summer League has packed up and left Las Vegas, and has long since vacated Orlando. LeBron James, Carmelo Anthony and most of their big-name free-agent friends have already signed new deals, leaving Eric Bledsoe and Greg Monroe as the only real players of consequence who've yet to score contracts of their own.

Fortunately for hoops heads, USA Basketball will soon be opening training camp in Sin City, with an exhibition slate to follow ahead of the 2014 FIBA World Cup of Basketball in Spain. The transaction-obsessed might find refuge in a blockbuster Kevin Love trade, should the Minnesota Timberwolves find a package that suits them anytime soon.

For the most part, though, the basketball world has gone silent. And since silence can be awkward, let's fill it with power rankings, guesses on where all 30 teams stand now based on what they've done so far in free agency, with a pinch of speculation sprinkled in where it's appropriate.
