"Antrel is a young, ascending veteran player, and he is an outstanding person who will bring leadership, versatility and more big play ability to our secondary," general manager Jerry Reese said.
Rolle visited the Timex Performance Center on Friday and met with Reese, head coach Tom Coughlin and the defensive coaches.
"I’m ecstatic," Rolle said after signing his contract around 11:15 p.m. "Words can’t really express how I feel now. I had five great years with the Cardinals organization. But I felt it was time for a change. The Giants are a first-class organization all the way. There are great opportunities for me, and I am excited to be working with the players I’ll be working with. I think the sky’s going to be the limit as to what we can do.
"I’m extremely excited for the opportunity, and I feel truly blessed. They have the confidence I can come in and be the player that they expect me to be, and I will live up to everything they expect and go beyond."
