Russell Wilson is a very good football player, and a fairly popular one as well. Something that often happens to those types of players is that the company they endorse gives them an official logo. On Saturday night, that happened for Wilson.
He shared a picture on Twitter of his official Nike logo.
It's a little strange looking. It appears to be one of those things where the logo looks like two different things; in this both an "R" and a "3," which is Wilson's jersey number. There does not appear to be a "D" in the logo for "DangeRuss," which is the tagline behind him in this picture (and also his Twitter name).
Either way, you can probably expect to see this logo on a boatload of Nike gear fairly soon, which will presumably be of great interest to Seahawks fans.
