Completing a two-day stretch of breakneck negotiations, the San Diego Chargers announced on Tuesday evening that they have reached an agreement with first-round draft choice Antonio Cromartie, a cornerback from Florida State. The 19th overall selection, Cromartie will sign a five-year contract, the maximum term permitted by the extension to the collective bargaining agreement for a player chosen in the bottom half of the first round. The contract can be worth as much as $12.75 million and includes $7.35 million in guarantees.
