Hull KR coach Chris Chester bemoaned the point that got away after watching Wigan score two late tries to snatch a 14-14 draw at the KC Lightstream Stadium.
Tries from Craig Hall, Jason Chan and Ben Cockayne had put Chester's men in a winning position at 14-4 with just eight minutes left.
However, former Hull KR playmaker Blake Green marked his comeback from a three-month injury lay-off by carving out a try for Wigan skipper Sean O'Loughlin and, in the final move of the match, England winger Josh Charney took Anthony Gelling's pass to cross at the corner to tie the scores.
Matty Smith's failure to land the touchline conversion at least earned the Robins a point but it was of little consolation to Chester.
"I thought we were the better team for 79 and a half minutes but, if you switch off for 30 seconds, a good team like Wigan will pull your pants down," Chester said.
"It's a cruel game but it just shows you've got to play for 80 minutes. We should have won that game."
The point moves Rovers to within two of eighth-placed Widnes and keeps alive their play-off hopes and, more importantly for Chester, restored their pride after a heavy defeat by the Vikings in their previous game.
"O ne thing I wanted from the guys was a bit of honesty and I think we got that," Chester said. "W e sat down as a group and addressed a few things. We spoke about honesty and belief.
"We are relying on other teams now but, if we get the same effort and commitment in the remaining games, we could still get into the play-offs."
Chester was delighted with the performance of Australian scrum-half Kris Keating, who was dropped earlier in the season but was back to his best against the champions.
"Neville Costigan probably had his best game for the club and I think we saw the real Kris Keating tonight," he added. "He has taken a lot of criticism but he really stood up tonight."
Charnley's last-gasp try spared Wigan a sixth defeat in seven trips into Yorkshire but they missed the chance to go top of Super League and coach Shaun Wane admitted his side were well below their best after a week off.
"I t was a point lost," Wane said. "I never saw it coming. We've been training really well but we don't seem to handle weeks off. Perhaps we will do something different next time.
"We were up against a team playing desperately to get into the eight and Chris has done a real good job so it was always going to be tough one but I am disapointed with our completion rate of 64 per cent.
"Our skill level was not good enough. It wasn't a Wigan performance - we didn't play anywhere near our standards."
