Donegal manager Jim Guinness believes that the new rules should allow for teams to use six substitutes in games rather than just five.
McGuinness was speaking after his team’s 0-20 to 0-16 victory over Dublin in Ballybofey, pointing to the fact that the Dubs lost three of their players to hamstring injuries over the 70 minutes.
"I feel for Dublin. They lost three players with hamstrings. I think that's definitely something that has to be looked at," the 2012 All-Ireland winning boss told BBC Sport NI.
"Peadar Mogan would be one of our fitter lads and he was really struggling at the end and we had the five subs on and we couldn't get him off.
"In the first document the FRC [Football Review Committee] put out, there were six subs and I saw that and thought that would be good and would take a bit of pressure off."
McGuinness also added that returning veteran Michael Murphy would’ve likely seen game time against the Dubs had it been played under the old rules.
"Probably if we were playing under the old rules, Michael would have been on tonight but we have to be very careful to make sure we're hitting all the targets before we decide to put him into action,” said the Tir Chonaill supremo.
