I know it's been done to death but the "I suppose" thing shows no sign of going away, particularly within the hurling firmament. It's getting worse if anything.
English football players used to routinely say the word "obviously" in interviews in the same manner, almost as a crutch. This mostly disappeared when foreign players began to predominate.
Any amateur linguists/psychologists/sociologists care to explain how and why a certain word or phrase becomes such a plague on the speech of a cohort of sportspeople?
Is there a copycat factor at work? Could it be even seen as necessary to utter the word/s in question to gain acceptance within a peer group?
