The Detroit Lions receive: Aaron Ross
The New York Giants receive: 2012 fourth-round pick, 2013 fifth-round pick.
The Giants have a very deep secondary at both the safety and corner position after the drafting of Prince Amukamara. With Kenny Philips, Michael Johnson and Antrel Rolle at the safety position and the possibility of re-signing Deon Grant, that was always an area of strength. The drafting of Prince Amukamara makes the corner depth even greater than it already was.
Amukamara will likely start from day one moving Terrell Thomas to the third choice. This in turn moves Aaron Ross to fourth choice. The team is heavily invested in Corey Webster who will be paid $8,000,000 next season and will need to fork out money for Amukamara.
Thomas is a very cost effective corner to keep costing only $550,000. Then Ross, who would be fourth choice, would be costing twice as much as Thomas. This is certainly not a huge amount of money but the team has many players it needs to re-sign such as Ahmad Bradshaw, Steve Smith, Kevin Boss and Barry Cofield. Keeping Ross for $1,000,000 makes little sense because Kenny Philips can also play his role and Joe Burnett is a capable option also.
The Lions would be attracted to Ross because he is a very talented former starter. At 28 years of age, he still has plenty left in the tank and would be an instant starter on the team. Ross could really flourish in Detroit taking advantage of what is expected to be a dominant defensive line.
Ross would be an upgrade over the team's starters from last season, Alphonso Smith—10 starts—and Chris Houston—15 starts—while also making those players better by moving them down the depth chart.
Smith showed some playmaking ability last year and the Lions would be smart to think that he could do even better matching up to team's second choice receivers. The Lions' secondary is frail to say the least at this point and it makes little sense for them to break the bank for Nnamdi Asomugha because they are not one player away from being a playoff team.
The Lions would be making a value trade picking up Ross. It has been these kind of additions that has brought the team back to respectability since Martin Mayhew took over.
Both sides would win in this trade because the Lions would be getting a quality player while the Giants pick up multiple picks and free up some cap space for the re-signing ventures that lie ahead.
