Oh please. Ask teams who have to play interstate or overseas and then back up in 5 days time in a different state or country how their re-hab and preparation goes. Players get bumps, bruises and strains all the time which, with 5 days of treatment, often see them fit to play. If you only have 5 days between games, and have to spend 1 day travelling, it means your 5 day winds up like this -
Day 1 - Travel home
Day 2 - Recovery
Days 3 + 4 - Training and prep for next game; and
Day 5 - Next game.
Only person disputing this is you mate. None of the clubs have, none of the players have, no other poster here has. It's not my job to comb thru hundreds of sports science websites to find research for you. If you can't comprehend what the issue is, then on this point there is no helping you.
Oh and by the way, as the clubs who regularly got the 5 days turn around pineapple (e.g. Cronulla, NZ Warriors, Knights) what it was like as opposed to teams like the Broncos which always seemed to get a 7 day turn around. Yeah getting that 87 day turn around never gave the Broncs any advantage eh?
Oh and by the way, if you want to say that an AFL game has as much contact and physical contact as the NRL, then you have real issues mated. You've been listening to Perth Red too much. Also AFL games have unlimited interchange.
As I said, the only comparable sport with as much physical contact and collision is NFL, and as I repeat, they cut down the pre-season by 2 games so they could add 1 additional regular season game. Even then, and NFL team comprises 53 players, of whom only 11 are on the field at any one time and can be changed at will and unlimited number of times.
The NRL? Has a 17 player saquad with the 4 on the bench only allowed on and off on a limited basis. It doesn't take Einstein to work it out.
I'm not going to respond anymore on this as you refuse to heed anything at all. You sound as dogmatic as PR.
