Morrison was nominated for March’s Sky Bet Championship Manager of the Month award on Thursday morning after going unbeaten last month.
He faces competition from Southampton’s Tonda Eckert, Frank Lampard of Coventry City and Matt Bloomfield of Oxford United.
“It’s a nice feeling for everyone and a credit to the coaching staff and the players,” Mozza said.
“But, it’s also a reflection of the hard work we’ve been putting in.
“It’s just about us keeping going with that belief and determination I keep talking about.
“I think the togetherness and the reaction from Oxford pleased me the most. The belief and determination from everyone to improve the performances and get out of this position.
“Sometimes you learn more from your failures and I think that’s the sign of a good team when you have that disappointment and you come back from it. We can control some disappointment, but it’s how you control the big disappointments and how you react to those.”
