Wood insists the core of the side used in France must be retained with the addition of one or two wildcard picks that could reap dividends in the future.
"Eddie needs to drip feed new guys in," said Wood. "I don't think there will be drastic changes. Eddie needs to win matches to stop speculation over his future, so I expect him to stick with what he knows.
"But he also needs to give fringe players more game time and take a gamble when he chooses his team.
"One gamble in a team is acceptable, not four or five. Then he has to stick with that player.
"He must avoid doing what England did with Mathew Tait after the 2003 World Cup, picking him and then dropping him. That was very unfair.
"He was an obvious talent and having picked him, maybe a little too early in my eyes, they had to stick with him."
Wood, who won 58 caps and was Brian O'Driscoll's predecessor as Ireland skipper, believes the players that misfired at the World Cup should be allowed to rebuild their battered reputations.
"These guys deserve a chance to prove themselves. The entire team played badly in the World Cup and that suggests it wasn't only them to blame," he said.
