Just watched the interview and didn't see anything wrong. If you are looking for something you would find it anywhere, if you weren't you wouldn't.
Interviewer: Can you shed some light on whether we will see Isaac Luke don the boots today?
Cappy: No, unfortunately we wont, Isaac hurt himself in our captains run yesterday, unfortunately, so we have a young Jazz Tevaga making his debut today.
not seeing a problem myself. Will we see Isaac playing? No he got injured so we have a new guy playing.
Were you looking at his eyes in the interview? Was he being shifty and not making eye contact, did he appear to be perspiring, how was his breathing? I'm pretty sure if you watch it again but don't listen to the words but just look for the signs it will be confirmed he was lying.
