Grizzlies owner Michael Heisley is a character. He appeared on the Chris Vernon Show recently and got into a…um…spirited debate over whether or not the Grizzlies should exercise a little-known clause in the collective bargaining agreement that allows for teams to negotiate a performance incentive into rookie contracts.

Xavier Henry is still unsigned due to Heisley’s insistence on this performance incentive. Rookie contracts are generally ‘rubber stamp’ type deals where the player gets the max (120% of the rookie scale) and he signs immediately. Heisley claims that the Grizzlies are not the only team to use this strategy, but he was unwilling to name any names and I certainly haven’t heard of any other teams doing so.

On the show, Heisley is passive-aggressive, condescending and entertaining, and in addition to the Henry negotiations, he defends the Pau Gasol trade, the Zach Randolph acquisition, and his decision to draft Hasheem Thabeet over Ricky Rubio.

Matt Moore of CBSSports called the interview an ‘abject trainwreck,‘ while Chris Harrington of the Memphis Flyer called it ‘borderline-embarrassing.’
