Everybody's got an opinion on what the New York Giants' biggest offseason need is, and the Giants have so many needs it's hard to tell anyone they're wrong.

My opinion is that the most important thing the Giants need to do in this year's draft is find a building-block defensive lineman who can rush the passer. The good news is this year's draft is absolutely loaded with defensive linemen.

Even if Ohio State's Joey Bosa and Oregon's DeForest Buckner aren't there at No. 10, that doesn't mean the Giants should trade down and amass more picks as fans often suggest this time of year. Clemson's Shaq Lawson dazzled in combine workouts over the weekend. His teammate, Kevin Dodd, offers the kind of size the Giants like in their edge rushers. Noah Spence is a physical freak who could be a difference-maker if his college drug issues are behind him. And interior defensive linemen like A'Shawn Robinson and Sheldon Rankins are strong options if the Giants don't fall in love with any of the pass-rushers.

Much of the Giants' energy right now is focused on trying to re-sign defensive ends Jason Pierre-Paul and Robert Ayers before the new league year starts on March 9 and they become free agents. They have not yet succeeded, and it's possible they could lose both players once the market opens. That would only make their defensive line needs more acute, and free agency offers only imperfect solutions.

But even if they get their wish and bring back both Ayers and Pierre-Paul, what the Giants need is someone around whom they can build their defensive line of the future. They need to be thinking about a big, fast, disruptive cornerstone player on the defensive line, and having the No. 10 pick in a draft like this year's should enable them to find one.
