Owen Coyle felt it was a missed opportunity as Rovers only collected a point on their travels at Rotherham.
Rovers had the better of the match for long spells at the AESSEAL New York Stadium, but found themselves trailing as Jon Taylor struck two minutes into the second half.
But Rovers pressed until the end and deservedly drew level when Connor Mahoney's corner was put into his own net by Stephen Kelly.
"There is no doubt that we should have won the game today," the boss told Rovers PlayerHD.
"We dominated the first half and probably should have been two goals up going into half-time.
"Then we come out at the start of the second half and lose a goal to a deflected shot that Jason Steele would have otherwise saved.
"But as disappointed as I am that we didn't get the three points, I was also disappointed with our reaction after going a goal behind. For ten minutes we were like rabbits in the headlights and that is not what we are about.
"So I made early changes to get us back into the game and from then on we dominated the game again. We got the equaliser late on and then had gilt-edge chances after that.
"It was a performance that we could easily have scored five or six goals today from some very good play. Their goalkeeper has made two unbelievable saves with the shots that struck the crossbar, Jason Lowe in the first half and Charlie Mulgrew in the second.
"Big Sam has chances, Danny also, but even right at the end Marvin Emnes's header looks all but in but it whistles by the post.
"But we wanted those three points and that is the disappointment."
Rovers are back on their travels this Tuesday night when they take on Sheffield Wednesday at Hillsborough.
