"Sometimes the coaching manual goes out the window. The goals have all been very different and if you'd told me it was going to be 4-4 before the game - and that it could have been 8-8 - I wouldn't have had it.
"I'm just disappointed we didn't win the game," continued Gray. "We've hit the woodwork twice but we can't afford to keep gifting teams goals.
"It was a nightmare for defenders with the conditions and we felt if we could have got the ball forward with a bit of quality then we could cash in against Scunthorpe's back four.
"We got punished for the mistakes we made and for a while it didn't look like we were going to punish them for the mistakes they were making.
"But then we pegged them back and capitalised on their fans' concerns."
A disappointeed Nigel Adkins blamed his defence for throwing away a seemingly comfortable 3 points.
"I thought going forward we were excellent," said the Iron boss.
"But we have got to defend much better than this. And if the personnel already here cannot do that, then I will have to bring some others in who can."
