In the three games that Darragh Lenihan and Tosin Adarabioyo have played together in a back four, Rovers have won all of them.
Lenihan returned from injury that kept him out of five Championship encounters after limping off against Queens Park Rangers in early October.
Since his comeback, Rovers have been rampant, defeating Barnsley, Brentford and then Stoke City.
Each win has been different, with the latest triumph at the bet365 Stadium showing Rovers' gritty side to win late on once again, responding just four minutes after a Stoke equaliser.
And speaking after a third win in seven days, Mowbray believes the partnership of Lenihan and Adarabioyo has been a cornerstone of his side's recent success.
“I thought Tosin and Darragh were immense at heading the ball out today," he revealed to iFollow Rovers after the game.
“We’ve had a situation this year of having a pretty direct team against us, where we didn’t head any balls out and we lost the game after being 2-0 up.
“Today, they stood up and were counted and got the job done.
“Tosin, you can see and I can see, he’s a high-quality, class player. We’re giving him an opportunity to show everybody his talents. How composed he is, how good he is with the ball and how he can make first contact on crosses and defend.
“Let’s hope we’ve found a good defensive partnership, but only time will tell.
“It’s easy for me to stand here and say we lost all those games because Darragh was injured, but I would say the personality of the footballer is what matters.
“When you’ve got leaders on the pitch, guys who have got it in their belly, they don’t even want shots at their goal, never mind goals going in," he added.
“When you see it every day in training, you need those players on the pitch. Days like today, when it goes 1-1 and the crowd are roaring, you need big personalities and characters.
"We were lacking them a little bit and now we’ve got them, and it’s helping the team.”
