Touchdown, Field Goal and Bullseye?

Detroit Lions had a big win Sunday over the Minnesota Vikings.  Last week the Lion's moment of the game would be the Touchdown Twerk.  But this week I think it would have to be the bullseye.  Here's the scoring break down as I understand it in the NFL.  Touchdown = 6 points, Field Goal = 3 points, Safety = 2 points, 2 Point Conversion = 2 points and of course the extra point = 1 point.

But Matthew Stafford clearly hit a bullseye Sunday and got nothing.  What's up with that?
