Ryan Nassib was supposed to be new Buffalo Bills coach Doug Marrone's guy with the No. 8 overall pick or when Nassib's former Syracuse coach traded down to the 16th overall spot Thursday. But when Marrone selected former Florida State quarterback EJ Manuel to be his guy, Nassib's stock tumbled.

That is, until New York Giants general manager Jerry Reese and coach Tom Coughlin stopped his fall at pick No. 110 on Day 3. Reese is always guided by the best-available value atop his board.

The Giants likely view Nassib as a backup upgrade over David Carr behind two-time Super Bowl-winning quarterback Eli Manning.

"If he doesn't ever play, that would be great," Giants general manager Jerry Reese said. "That's a good problem to have. If he needs to play, we're hoping that whatever time that is that he'll be up and ready to go."

The Giants have four quarterbacks on their roster -- Manning, David Carr, Curtis Painter and Nassib.
