Also according to Mike Florio of ProFootballTalk.com is this nugget:
On Saturday, Leinart’s career hit the unscripted portion when he was cut by the Arizona Cardinals when no team was interested in trading for him. Worse, few teams are interested in him. The Seattle Seahawks and coach Pete Carroll, Leinart’s coach at USC, have a need and could be interested. Likewise, the Minnesota Vikings and Jacksonville Jaguars are kicking the tires on Leinart.
I personally don't think they have any interest.
