I think it's Russell Wilson's...
The Seahawks loaded up on offensive targets, are FINALLY allowing him to really toss the ball around, and they had zero pass rush, so all their games will be shootouts, which leads to major numbers.
Unless Wilson turns the ball over or they lose a good number of games... or if the NFL MVP is becoming the heisman where the new shiney second year QB gets it every single year Kyler Murray.
