Giants collecting CBs, add Zack Bowman

Our man Adam Caplan says the New York Giants have agreed to a one-year contract with free-agent cornerback Zack Bowman. That makes 20 free-agent signings for the Giants so far this offseason, four of whom play cornerback.

Bowman, 29, is known as a strong special teams player. So even if he can't find a way into the suddenly crowded mix at defensive back, he's likely to make a contribution on the kick and punt coverage units. But he did start seven games for the Bears last year and had two interceptions during that stretch.

The Giants this offseason already re-signed cornerback Trumaine McBride and signed veteran cornerbacks Dominique Rodgers-Cromartie and Walter Thurmond from the Broncos and Seahawks, respectively. Rodgers-Cromartie and Prince Amukamara project as starters, with Thurmond apparently ticketed for the slot corner role. But with Thurmond, McBride and now Bowman on the roster, all of whom have experience as starters on the outside, the Giants count the cornerback position as the deepest on their roster.
