I think Caro actually makes decent yards after the collision. The lack of data gathered from champ games continues to frustrate me so unfortunately we can't really back our opinions up with any solid data. It's funny how some people think the exact opposite though.
We don't make the most of his height anywhere near enough. Attacking kicks to his wing were few and far between last season. He also seems to be terrified of the touchline, which is not an ideal trait for a winger to have.
Still, I'd give the starting wing spots to Ryan and Caro at this moment in time. If Macani wants a run out he has to earn it.
