Jackie Tyrrell has backed Dean Rock after a price list, purportedly from the Dublin All-Ireland winning footballer, for free-taking lessons was circulated online.
A number of former inter-county footballers like Kieran Donaghy and Eamon McGee have leapt to Rock's defence since the price list first emerged on social media this week and sparked debate and discussion in the context of GAA's amateur ethos.
Speaking on the RTÉ GAA Podcast, Tyrrell pointed out that services provided by many non-playing members of clubs and inter-county teams are not always voluntary.
In that context the former Kilkenny All-Ireland-winning hurler backed Rock for coming up with a business idea based around his sporting talents.
"First of all, if it is confirmed, for Dean Rock it's a very brave and bold move to create a business out of his talents and I would say more power to him on it," Tyrrell said.
"You look at the GAA as a whole, how many managers are getting below the radar payments? Take a club or an inter-county team. Physios, they get paid for their services, nutritionists get paid for their services.
"If it's a free-taking or a goalkeeping coach, they get paid. So right across the broad spectrum of the GAA, there are payments.
"If he gets what he's supposedly charging for it, more power to him, and if people are willing to pay that, that's their decision.
"He's put it out there that he's willing to do whatever he wants - coaching, one-on-one lessons, multiple sessions - and he's offered that service."
Tyrrell added that it fits within the current lay of the land.
"People are making money out of GAA, people are getting jobs," he said.
"Personal trainers are making huge money and it's a hugely demanding job because it delivers success.
"Because it's something new, because someone is doing something different that hasn't been done in the GAA, there is this whole uproar and this heated and toxic conversation."
Tyrrell also pointed to Rock's involvement in charitable efforts off the field and how that has not been highlighted in online commentary.
