The Vikings have signed DeMarcus Van Dyke, according to Rand Gettlin at Yahoo! Sports.
The #Vikings have signed speedy CB DeMarcus Van Dyke to a one year deal, per a league source.

Van Dyke is largely known for his speed, as Gettlin alludes to, having had run a 4.25 40-yard dash at the NFL Combine in 2011 (officially a 4.28). This isn’t quite a Josh Robinson, however, as Van Dyke is not as physically adept overall as Robinson, with a low vertical and a bad weight for a CB (on the other hand, he isn’t short).
The weight and speed both come from a track background, where he was more committed to running track than football, though he wasn’t bad at Miami (FL) as a football player. He recorded two interceptions his senior year. He only returned one kick at Miami (unusual for his speed) for 26 yards.
That obviously isn’t the entirety of his contributions, but it does put his physical talent into some perspective. Van Dyke, like Josh Robinson, was picked in the third round though this time predictably by the Oakland Raiders and lasted a year on their roster. He was released on September of the following year after making it through training camp, where the Pittsburgh Steelers picked him up. There, he stayed on the roster until he was waived with an injured designation on the cutdown to 75, and put on injured reserve until he reached an injury agreement with the Steelers.
