An effort by the Green Bay Packers to sign cornerback Kyle Fuller ended when the Bears matched the offer sheet. Chicago had put the transition tag on Fuller before the start of free agency — meaning he could negotiate with other teams, but the Bears had the right of first refusal. Green Bay’s lack of cap space was a factor in the miss. Now, three of the top cornerbacks are off the boards. If the Pack doesn’t find somebody, it will have an awfully-young defensive backfield because the positions will be filled through the draft.
