Runaway Celtic League champions the Ospreys have expressed their disappointment that none of their front five forwards made the Lions tour.
Brent Cockbain, Barry Williams, Duncan Jones and Adam Jones were thought to be in contention, but all missed out.
"I really feel that Duncan would have added a lot to the Lions squad, he's a magnificent player," Ospreys manager Derwyn Jones told BBC Sport Wales.
"Brent was a bit unlucky and we also think that Barry was good enough."
The Ospreys players in Lions coach Sir Clive Woodward's 44-man squad are backs Shane Williams and Gavin Henson.
Blues prop Gethin Jenkins was the only Welsh front five player to make the tour, team mate Martyn Williams and Dragons number eight Michael Owen the other forwards.
Included amongst the 20 English players are 36-year-old England retiree Neil Back and Richard Hill, who missed the entire international season with a serious knee injury.
Duncan Jones and 1997 Lion Barry Williams lost out to Sale's England back-up prop Andrew Sheridan and hooker Andy Titterrell.
"Duncan's really put his hand up in the last couple of seasons and was very unfortunate to break his thumb at a crucial time before the Six Nations," said Derwyn Jones.
"But with guys like Richard Hill, Sir Clive has taken into account performances over a long period of time.
"Some of the other selections have raised a few eyebrows, but at the end of the day Clive has won the World Cup and you have to go with his judgement."
Woodward himself named Cockbain along with Dragons full-back Kevin Morgan as two Wales players who were unlucky to miss out on selection.
But he qualified his statement by saying it was impossible to please fans from England, Ireland, Scotland and Wales.
"Even if we'd named a squad of 60 or 70 there would have been people unhappy," Woodward told BBC Sport Wales.
"If I was the sort to worry about all the criticisms of my selection then I'd be in the wrong job."
