Er, you've got it exactly backwards. Anyone nominated is not going to be hosting SNL, they'll be in LA getting ready for the Oscars. In fact, they'll have problems getting any big film star to host that weekend, because no one is going to want to work a full week at SNL and then take a red-eye flight across the country to appear at the Oscars
But after Russell Wilson leads the Seahawks to victory--which he will--he would be a good pick to host as the first black QB to win a Super Bowl. He might actually make a good host. He's smart and well-spoken.
