Vikings free-agent cornerback Chris Cook, who visited the team today, will sign a one-year deal, according to a league source. Cook, 27, was a disappointment in Minnesota both on and off the field, and he ended his four-year stay there without an interception. However, at 6-2 and 212 pounds, he has the height, athleticism and the long arms general manager Trent Baalke has been searching for in a press cornerback. The terms of the deal are not known, but there was not a high demand for Cook and the deal is likely to be team-friendly and similar to the ones signed by troubled cornerbacks Perrish Cox and Eric Wright in recent seasons.
