Rovers played out a 3-3 draw with Bradford in midweek, and although O'Driscoll reckoned the crowd will have gone home happy he wants his side to be sharper at the back.
He said: "It was an exciting game, but we probably had more chances than them despite being behind in the first-half.
"We just needed to tighten up in defence, and once we did and managed to get a goal I thought we deservedly went in front.
"We were at fault with some poor marking at times but we always looked likely to score."
