Injuries permitting, Gareth Thomas, Shane Williams, Tom Shanklin, Gavin Henson, Stephen Jones, Dwayne Peel, Gethin Jenkins, Martyn Williams and Michael Owen would all appear to be leading contenders for a tour highlighted by three Tests against Graham Henry's All Blacks.
Flanker Colin Charvis, who missed the Six Nations due to a broken foot, is another strong candidate and, given Wales' dominance of this season's tournament, the list could stretch well into double figures.
"The players have done the business, and I wouldn't be surprised if there are 10-plus Welsh players on the tour," said Ruddock.
"At the minimum, 10, and I would have thought there will be a lot more.
"I am quite excited about the fact that a lot of players could go on the Lions tour and come back with a lot of good experiences and further their rugby development."
