RGIII has better stats in almost every area including Total passing yards, pass completel %, half of the interceptions Wilson has. Also has significantly rushing yards and also more rushing TDs.
Wilson has 5 more pass TDs. Wilson also has a WAY better defense this year that has set him up a lot.
Wilson's total completion percentage is better (factoring drops and throwaways). Of his ten interceptions, five came on receiver drops or slips. One came on a Hail Mary at the end of a half. One came when he was hit while throwing. Only three could really be considered his fault.
So we have two QBs with very similar stats (RG3's only real edge is rushing yards, of which he has about 400 more than RW). The reason I give it to Wilson is that his struggles came at the beginning of the season with a first string offense that he had never played with. Since Week 5, Wilson has been the best QB in the league with better stats than RG3. That, combined with Cousins' good outing, puts Russell ahead in my mind.
