He never played all 16 games and has yet to record a single interception in his NFL career. But he seemed a player almost from the get-go that wasn't an ideal fit in the Tampa-2 defense the Vikings ran during his run with the team.
Cook had the size and physicality to take on wide receivers one-on-one, but in the Vikings defense he wasn't often asked to take a receiver deep down the field on his own. Largely viewed as a bust, Cook got a new lease on life by heading west to San Francisco, who signed him Friday to a one-year contract.
The 49ers are a team in need of cornerback depth. They cut Carlos Rogers for salary cap reasons and lost Tarell Brown in free agency when talks on a contract broke down last week. They are in a cold war with Seattle and need to keep pace. Cook may not be the answer, but, at a minimum, he is going to get a chance in another environment.
Vikings fans aren't going to see the loss of Cook as anything significant. Panthers fans are going to miss Captain Munnerlyn considerably more. But perhaps if Cook gets in a system that plays to his strengths, he can find the NFL career he wants – not the one he had in Minnesota.
