Johnny Mullins cancelled out Kevan Hurst’s opener when he fired home at the back post after a goalmouth scramble, a result Evans felt they deserved.
“I thought for an hour we were simply outstanding,” said Evans. “In the first half we were the dominant side which is hard to be here at Roots Hall.
“We opened them up time after time and we could’ve executed some situations better before they scored a wonder strike through Kevan Hurst.
“After that, the substitutes I brought on inspired us to get the point and we showed a lot of passion and character which is excellent to see.
“I didn’t think it was going to be our day but we got some dangerous balls into the box which in the end gave us the equaliser.
“It is another game on our quest for promotion and I believe we have the team here capable to get up.”
