I honestly thought Kibula really struggled. He did have one great run though.
He came out way too fast in defence and made some poor tackle attempts resulting in high tackles. That may well be over enthusiasm on debut.
A good comparison is Kibula and Matty English. Very similar in age, but it's clear that Matty English is way ahead of Kibula currently.
The main thing for Kibula will be game time. Once he gets up to super league fitness and speed I believehe could be devastating. But he's got lots of hard work ahead of him and needs to stay patient.
Let's be honest, seeing a huge guy taking a hit up is always a great sight.
