"In a way, it is affordable to think that a team should be allowed to substitute an injured player in a Test match, more than a One-dayer," Woolmer was quoted as saying in a leading Indian daily The Indian Express.
Injuries, he points out, occur more in a five-day game and he personally deems it's less necessary for One-day cricket to apply the same principle.
"Over five days, it makes more sense."
Contrary to conventional wisdom, Woolmer says it's good news for the specialist player.
"I feel it will put all-round cricketers under pressure as it would be easier to pick seven up-front batsman and then substitute one for a bowler when batting first."
Woolmer, currently on holiday in South Africa, however feels that substitution in One-day cricket shouldn't be helping players to leave the field, in case they're tired.
"I guess there is that chance but modern day cricketers need to be fit enough to last 50 overs," he says.
What most excites him is the change in rules covering field placements.
"There will be some serious tactics involved here. The captain will have to decide which two five-over periods to invoke the field settings. No doubt this will be when there quiet periods in the game," he says.
"If, for example, there are early wickets taken, then the fielding side can go up to the first 20 overs without a change. But I would prefer a provision that the slotting of five-over periods be allowed only after the first 25 or 30 overs.
In any change it's easy to see both positives and negatives," he says and adds, "But I would rather be experimenting with all this and if it does not work, it can always be thrown out."
Woolmer also added that the ICC could have tweaked the changes slightly differently.
"For example, the most important change should have been with the white cricket ball and its tendency to discolour."
"A new ball at 25 overs," is what he suggests.
