The Vikings knew they had to add insurance at cornerback given the season-ending ACL injury to Cedric Griffin in the NFC title game and the fact that Antoine Winfield, entering his 12th season and turning 33 this summer, also is coming off an injury-marred season. And most assumed the draft, and perhaps the team's top pick, would be the route the Vikings took to solve that immediately. But the team made a nice signing on the eve of the draft with Lito Sheppard, a former starter with the Eagles and Jets. Sheppard has played in a lot of man-cover schemes and likely will have to adjust to the Vikings' zone-heavy system that asks the corners to be tough, quick in short areas and redirect receivers off the line. Although it's not what Sheppard is known for, he could provide some short-term insurance in the starting lineup and safely land thereafter in the slot if both Griffin and Winfield are healthy.
