Striker Green has now been on the bench for five games and, having come on to score winners in the previous two matches, this time he bagged an 81st-minute equaliser.
Before that Wycombe had looked set to chalk up a first away league win of the season thanks to Matt Bloomfield's 23rd-minute goal.
"I think it would have been criminal if we didn't get anything out the game. But it was frustrating again," said Murray.
"I blame society. I have told them in the dressing room I am going to ban all kinds of social media, mobiles phones, the lot, from being in the club as no one talks any more. I think the world has gone.
"No one talks, no one communicates. Then we expect to go onto the football pitch and communication and leadership are going to be there and it doesn't happen.
"For the first 60 minutes it was like we were stuck in sludge. No one spoke. There was no fire, no aggression, no will to run. The game was there for us today and if we'd wanted it for the last 60 like we did for the last 30 we win that game.
"If we want to get promoted, it's there for us. It is as easy or hard as they want it to be. But they've got to grasp it."
Wycombe took the lead when Paul Hayes split the home defence down the centre to send Bloomfield in for a calm finish from 12 yards.
Scott Shearer made two saves to deny Dominic Gape and Adebayo Akinefenwa as Stags clung on.
A double change at the break brought Mansfield to life and Green and Mal Benning went close before the former's fourth goal in three games levelled it.
It then took a great save from outstanding goalkeeper Jamal Blackman to deny Darius Henderson a stoppage-time winner.
Wycombe boss Garth Ainsworth said: "I am so proud of the players.
"We played all of the good stuff in the first half and a lot of it in the second half.
"There was a bit of a panic at the end and we couldn't get out of our own half. There was free-kick after free-kick coming back at us.
"But we ground out a result and that is fantastic. I am really pleased for the boys and the fans.
"There was a blatant push (on Danny Rowe) and foul for their goal. And I disagree with the decision for the free-kick that led to the goal."
