As per several sources, the Steelers have signed fifth-round pick Dennis Dixon to a three-year contract that includes a $130,000 signing bonus.
Also, don't make too much of the Rooney family's shifting of some of the team's stock. This is something that has been coming for some time now as the NFL works to remove itself from any kind of gambling.
The family itself doesn't want to divest itself of its race tracks or the football team. You won't see the team sold to an outside source anytime soon - if ever.
