Walsall were second best for most of the first half, but Hutchings would not reveal what he had said during the interval to turn things around.
After the 2-2 draw, he said: "That's between me and the lads, but the dressing room needs painting again.
"We conceded a bad goal in their first attack, and in fact they scored twice in their first two attacks which gave them something to hang onto.
"It meant we had given ourselves a mountain to climb, but in the second half I thought there was only going to be one winner, but Darren missed a gilt-edged chance. We were staring defeat in the face, but the lads showed great character in coming back."
