Worsfold said the NAB Cup had obvious value and he was certain pre-season matches would remain in some form next year when the competition expands to 18 clubs and a longer regular season.
However, the coach said players did not need extensive match practice to make sure they were ready for round one and the AFL needed to consider the demands of the regular season when devising a pre-season format for 2012.
"I would think that there definitely is [such] a thing as too much footy," Worsfold said from Patersons Stadium on Thursday.
"The players are pushed right to the limit every week to get up and play. They look pretty exhausted by season's end at the moment, so I think that's something that needs to be taken into account.
"It does have obvious value. So if the NAB Cup's part of our preparation for the season, I'm rapt with that.
"If it's not, it'll be a different format. We'll just call the practice matches the NAB Cup and we're back to where we started."
The AFL is yet to make any decision on the pre-season format beyond this season, with National Australia Bank in the final year of it's five-year deal with the League.
While acknowledging the value of the pre-season competition, Worsfold said it was a myth that players needed practice games to prepare for round one.
"I don't necessarily think they need any," he said. "I think players can train and be ready to go round one. A lot of players play really well first round of the NAB Cup.
"It's obviously been a big part of the AFL tradition, but we see players coming back from injury - top-line players that have been out of the game for six weeks or so - they come straight back into AFL footy and play really well.
"If you looked at Nick Riewoldt last year, he missed 10 or 12 weeks. He didn't need practice games to come back in and play AFL footy, he just came back in and played.
"I would challenge the myth that we need to have practice games to be ready to play round one."
Worsfold said club fitness staff used the NAB Cup to prepare players physically, but there were alternative ways to make sure players were match fit ahead of round one.
The Eagles enter this Saturday night's NAB Cup semi-final with close to a full squad to choose from, with Beau Waters, Darren Glass, Andrew Embley and Mark Nicoski all returning to face Collingwood at Patersons Stadium.
Only Sam Butler (thigh), Jarrod Oakley-Nicholls (ankle) and Daniel Kerr, who is returning from a serious hamstring injury, have been ruled out through injury.
Worsfold said Kerr was a chance to play restricted minutes next week, either for West Coast or East Fremantle in a practice match.
"We'll make the call on whether we want him to play 30 minutes of footy at some level or whether we wait another week so he comes in and plays 50 or 60 minutes straight up," the coach said.
Daniel Kerr is a $196,800 midfielder in the Toyota AFL Dream Team competition
