NFL free agency opens March 13th, and one player on the New York Giants that teams will be looking at is Mario Manningham.

Manningham, who at one point was the No. 2 receiver on the depth chart coming into last season, was downplayed by another great year by Hakeem Nicks and Victor Cruz.

Despite that, he managed to have 39 receptions for 523 yards and four touchdowns.

But his biggest success came during the postseason, where he had three touchdowns and that excellent catch in the winning drive of Super Bowl XLVI.

But now, he's about to become free agent, and the Giants have to consider whether or not to keep him.

Here are 10 reasons why he should stick around.
