The Owls operate with a system which requires them to win the ball high up the pitch and if their pressing game isn't executed properly by their strikers, then Gray feels that hinders the whole side.
“We defend from the front,” Gray said. “Last week at Blackpool we had Atdhe Nuhiu and Will Keane closing down their defence and winning the ball back.
"The games where we’ve struggled are the ones where we’ve not done that."
Wednesday place a huge amount of importance on being organised throughout their side and it is easy to see why Gray feels that their game-plan unravels when their strikers do not put the effort in.
The Yorkshire side have the second best defensive record in the Championship, but their lack of goalscoring threat means it is hard for them to hit back when they do fall behind.
Wednesday clearly lack a potent goalscorer and their tally of 32 goals in 38 league matches is the second lowest in England's second-tier.
It is not exactly a glowing endorsement for their current front-men and Gray has recently stated to the Star that he will be looking to bring in a new striker this summer.
Wednesday now have money to spend and signing a goalscorer will be high on their list of priorities in the next transfer window.
It seems, though, that whoever they do bring in will have to offer more than just goals, as if his work-rate is not exemplary then he won't be able to fit in with the team's demanding system.
