Leigh face Rochdale in the Championship on Sunday and a week later the sides meet again in the Challenge Cup.
Rowley says he was impressed with Rochdale’s win over Batley last Sunday and believes they are finding their feet following promotion.
“Their win shows what a competitive league we’re in,” said Rowley.
“Rochdale struggled for form initially but typically they look to be improving just as we’re about to play them two weeks in a row.
“They have some players available to them from St Helens and even though they are currently bottom of the table and we are top, recent results have proved the quality of the competition.”
Centurions are without Martin Aspinwall for Sunday after he suffered broken ribs against North Wales crusaders.
Several Leigh players were the victim of a sickness bug or suffering from flu last weekend and Rowley said that contributed to a performance which he described as “lacking energy”.
Matt Sarsfield also played despite tonsillitis.
