Theories Tom Brady could come out retirement for a third time and play for the Las Vegas Raiders have run wild in recent days - but recent history suggests the precedent has already been set.
Brady is awaiting approval from the NFL to become a minority stakeholder in the Raiders, something that's not expected to be an issue. But following injury problems to new quarterback Jimmy Garoppolo it's been speculated that Brady could step in if he invests in the team and they find themselves in need of an experienced starter.
There's been two instances in recent history where staff members not on the playing roster have been denied the chance to play at short notice. Brady's case could be viewed differently but due to how the Raiders would likely structure their salary cap to force he situation, the unanimous vote needed from the other 31 teams would be in serious doubt.
