3DowNation brought you the news that Dart Guy was planning to attend the Argos home opener and he did he ever: decked out in full Argos colours, including a blue beard.

Jason Maslakow has added more shades of blue while turning his attention from the Maple Leafs to the Argos.

Even Ticats fans, who are known well for hating the Argos, were thrilled to meet Dart Guy.

Maple Leafs forward Mitch Marner made the trek down to BMO Field on Sunday for his first Argos game.

The 20-year-old Markham, Ontario native played in 77 games for the buds last season scoring 19 goals and adding 42 assists.

Perhaps Dart Guy and his positive mojo that carried over from a strong Leafs season has given the Argos a boost like the Popp-Marc Trestman tandem.
