I think it takes the oxygen away.
"RFC is aware of the rumours regarding the coach being sacked. They are false. Hardwick will be our coach in 2021 and beyond."
Issue over.
While that may be true, it may also encourage other rumours to be started knowing that it will illicit a response from the club.
And what if there are 3 rumours every week? Does the club then have to release statements for every rumour?
