The English centre-half helped the Hoops to last season's championship but he has been a much more integral part of Neil Lennon's side this time around which gives him more pride as the Glasgow giants head towards a second straight premiership.
"I've played a lot this year. I think this has been the most I've played in almost three years," he said.
"I had my issues in my last season at Nottingham Forrest, I wasn't training or playing, and then at Celtic I've had injuries or not been able to get into the team because they have been doing well.
"But this season has been a good run for me and I'm enjoying it. When you enjoy it, it makes it easy, but if you're happy with personal things, it's 10 times easier and that's how it's been this year.
"I think winning the league this season would mean even more to me than last year. Things weren't right on a personal note so I didn't enjoy it as much as I could have.
"A lot of things have been right this year - not perfect, but right - so I've got on with my football and I think it's shown."
