Junior Hoilett grabbed an equaliser for Rovers after Lee Bowyer had put the visitors in front and although there were not many chances in the second half, Kean felt that his side could have capitalised.
It was Rovers' third consecutive draw and Kean said: "I wanted to take a big leap today but we're taking little steps and we just have to keep chipping away.
"If all the teams around you pick up wins and you only get a point you're massively disappointed.
"But today we're probably a little bit better off than when we started."
Kean added: "Junior has shown he can play on any side and if you're a defender and he's running at you he can petrify you with his touch and his pace."
However the hard-earned point came at a price with Hoilett limping off with a tight hamstring and Ryan Nelsen and Roque Santa Cruz also having to leave the pitch early.
Kean indicated all three substitutions were precautionary and added: "The atmosphere in the dressing room is really down. But we will soon come to realise that this is a good point today."
