The Eric Bledsoe clause...
"This stance against the “we’ll-match-any-offer” rhetoric is right in line with the approach NPBA executive director Michele Roberts has taken since she started as the leader of the players’ union. It’s exactly what she should be doing. Restricted free agency is a tricky issue, because the NBA wants teams, particularly those in small markets, to have a mechanism to keep their young stars, and the players want the freedom to choose their own teams.
There is some merit to the idea that a team saying publicly that they’ll match all offers can kill a player’s earning power and leverage. Under normal circumstances, Eric Bledsoe would have been one of the most sought-after free agents on the market last summer, but teams were so convinced that the Suns would match their offer sheets that they showed no appetite whatsoever for going after him. Bledsoe dangled in restricted free agency until almost the start of training camp, when he finally agreed to a five-year, $70 million deal to stay with the Suns. Roberts wants to prevent a similar situation from taking place with someone like Butler or Middleton."
