The need is there but the ability to satisfy that need might not be there, which is why the Giants’ desire to land Vonta Leach is likely to go unfulfilled.

With a serious knee injury to Henry Hynoski creating a void at fullback, the Giants have keen interest in Leach, perhaps the best blocking fullback in the NFL, but in order to acquire him they will have to be “creative’’ in the way they structure the deal.

“Vonta will visit if the Giants ask him to,’’ Leach’s agent, Ralph Vitolo, told The Post Wednesday. “No team has been excluded. The Giants are a great fit also, but we have to be creative.’’

Clearly, the Giants do not have the salary cap room to make Leach, 31, an offer he will jump at, meaning they remain a long shot to get the former Raven and Texan. The Dolphins have emerged as the favorite landing spot for Leach, as Vitolo earlier in the week told the Miami Herald he believes the Pro Bowl fullback will eventually sign with the Dolphins.. The Texans are also interested.

Vitolo told The Post he continues to talk with the Dolphins “and others.’’

The Giants are only $3.3 million under the salary cap and have yet to sign two of their draft picks, first-rounder Justin Pugh and fourth-rounder Ryan Nassib. The need for a fullback arose this spring when Hynoski went down with a freak knee injury in the first organized team activity practice. He suffered an injury to his medial collateral ligament and also a chip fracture to the lateral plateau of the left knee and underwent surgery on May 24.
