For one thing, Wright has a lot more skills than just catching the ball and putting it over the line, he's a very complete player.
More generally, I don't think the 'signing league players is always doomed to fail' argument stacks up. Yes, there have been some momentous failures (Moeroa certainly one) but I would suggest there have been plenty of successes too. Mat Rogers, Lote Tuqiri, Isi Folau before he went all homophobic, and plenty more.
Also depends what you want to classify as league players.
Rocky Elsom and Wyclif Palu were both in the league system before playing Super Rugby.
