Darren Ferguson felt his side were good value for a point at Southend United after the 0-0 draw at Roots Hall.
Rovers' clean sheet against the Shrimpers was their second in their past three games in Sky Bet League One, and the manager praised the team's determination.
He said: "I am really proud of the team, we had to change things 10 minutes before kick-off which isn't ideal but I felt Matty Blair came in and did a really good job.
"The back four were strong against a really good side, Southend have beaten Wigan and Portsmouth at home recently so it was always going to be tough.
"I thought we caused them problems which was pleasing because the pitch wasn't helping either side, there were times when we had to dig in towards the end and we managed to do that."
Rovers now have over a week before their next league game against Bradford City on Monday March 19, and Ferguson is planning on using that time wisely ahead of the clash against the Bantams.
He added: "We've got a while now before the Bradford game, we will make sure we do things at a good intensity and give the players enough rest with it being such a long week leading up to the game.
"We've got a few players coming back into contention who will make a difference for us at a stage of the season where it's important to have options, we have to find the right balance with things.
"At this time of the season the intensity levels stay the same, but the time you're working doesn't as recovery is the most important thing. We'll use the players as much as we can."
