Ask the Giants about their special teams play and plenty of different adjectives come up from awful to infuriating. But the most ubiquitous — and accurate — is embarrassing. Big Blue has surrendered three punt returns for touchdowns while the entire rest of the NFL has allowed just four. And with Philadelphia’s DeSean Jackson who has a history of torching the Giants looming Sunday they really only have two options: Fast improvement or further humiliation. “Awful’’ special teams coordinator Tom Quinn said. “It’s frustrating. It’s not what our expectations are. It’s not what the organization the team mine Larry [Izzo special teams assistant] anyone. “It [ticks] you off and I hope it [ticks] everyone off in this building. To take away a shutout from the defense that hurts.’’ Quinn was referring to allowing Marcus Sherels’ return in Big Blue’s 23-7 Monday night win over Minnesota a game the special teams forced two turnovers but lost a fumble themselves. But their coverage units have been sieve-like all season coughing up an 81-yard touchdown to Denver’s Trindon Holliday and an 89-yarder to Kansas City’s Dexter McCluster. “Yeah it’s embarrassing for us because we know the New York Giants as an organization take pride in their punt and kickoff — all special teams the whole thing but punt is a major role for us’’ linebacker Jacquian Williams said. “We’re definitely embarrassed and we’re definitely going to improve on it from here on out.’’ After not allowing a punt or kickoff return for a score last year they’re next-to-last in punt coverage with a field-swinging 20.4 yards per return. While Quinn claimed it’s not any one thing linebacker Spencer Paysinger acknowledged there’s a clear commonality with all three scores — not shedding blocks.
