It's hard not to be impressed by the way tight end Colson Yankoff has gone about his business this summer. Colson Yankoff is making some serious noise at Commanders campThere doesn't seem to be a practice that goes by without Yankoff making an exceptional catch. Strong preseason could help Colson Yankoff increase his Commanders roleThey know what he can do on special teams, and he is showing encouraging progress as a blocker. I don’t know how it has to work, but the Commanders have to keep Colson Yankoff. And he will be a player Commanders fans should monitor extremely closely when the preseason begins.
