Football is lost and won in the trenches.

They hope the latter will set the table for the upcoming season, but in the words of president and chief executive officer John Mara, they need to give quarterback Eli Manning "a little bit of help, particularly on the offensive line, I believe."

**>> GIANTS DEPTH AT O-LINE**

With offseason workouts and the draft right around the corner, Giants.com looked at the state of the offensive line and identified these three questions moving forward:

1. Who plays center?

Prior to the start of free agency, the Giants waived J.D. Walton, who started all 16 games in his first and only year with the team.

The move came after they signed Brett Jones from the Canadian Football League. 

Jones started all 20 games at center last season when he was named named the CFL's Most Outstanding Offensive Lineman and his Calgary Stampeders won the Grey Cup.

But the Giants could turn to 2014 second-round draft choice Weston Richburg, who cut his teeth in the NFL starting at guard last season.

When asked at the NFL Scouting Combine in February about the preferred position for Richburg, coach Tom Coughlin said he is a center and "will have every opportunity to compete." Richburg lined up at center for 45 games at Colorado State.  

2. How is Geoff Schwartz?

The Giants placed 22 players on injured reserve in 2014, and unfortunately, the 6-foot-6, 340-pound Schwartz was one of them. Missing the first 10 games of his Giants career with a dislocated toe, Schwartz played and started two games before suffering a season-ending ankle injury.

At the NFL Annual Meeting in Phoenix last month, Coughlin said that he saw Schwartz recently and that he "looked good."

3. Will the Giants add another "big human" in the draft?

One of Coughlin's biggest points heading into the offseason is that the Giants need to run the ball more effectively as well as stop the run. In order to do so, you need big humans, as the head coach likes to say. And you can never have enough.

"We are trying to improve," Coughlin said at the league meetings when asked about the state of the offensive line.  "We are improving both sides of the ball. I feel strongest when I feel that our O-line and D-line are in position."
