Or he might have taken a long term view with some of his big name players coming back from injuries. What's the point of playing someone coming back from injury when you might end up losing them for longer if they worsen the injury? We'll have played 15 tests by the end of the year. Player welfare has to come into it sometimes.
What injury did Tupou have?
I get he didn't play well for the tats but he's clearly world class and with Skelton not available the first test it was obvious he would've been needed
also not having White or JOC in the camp to begin with was a obvious flaw, you need experience especially given those two players have prob won more pro trophies than the rest of the backs combined, even if it's just to benefit the young players in the training camp.
Zero to do with injuries.
