The championships, viewed as a showcase of future world stars and televised live on Sky, kick off on 5 April and Scotland face Australia, Wales and Japan in the pool stages. But having lost all four international games in recent weeks Wright accepted that the team's goal of finishing in the top eight - they are seeded tenth - will be tough due to the current gulf in preparation between Scotland's youngsters and the world's leading nations.
"We have a very good squad, very talented lads, and the fact we have no injury problems means we have the best squad available," he said.
"But there is no doubt that we are under-prepared compared with the teams we face."
Cameron Ferguson captains the side and others tipped for a career in the game are the Edinburgh and Stewart's Melville FP winger David McCall and Graham Hogg, the Hawick centre.
