Buckley focused on securing jersey
Tony Buckley insists a run of games would help solve one of the great enigmas of Irish rugby.
Buckley has often hinted at devastating potential - most notably against the All Blacks in New Zealand last year - but has too often failed to deliver.
An opportunity to shine will come in Sunday's World Cup Pool C clash with Russia, and Buckley insists he requires ownership of the jersey to prove himself.
"I have been all over the place. Last November against South Africa I played brutal and got injured," he said.
"Two weeks later against Argentina I was back and we did well, driving them off the ball. There were a few good things that happened.
"Two weeks after that I played the Ospreys and that was a nightmare, personally.
"It's been improving over the last few months. I just need a run of games and staying injury free. Trying to get games at tighthead is what I want.
"Last year up to the Toulon game at Thomond Park I was feeling really good, scoring two tries.
"I was looking forward to boxing on from there, but then my momentum was killed after that. Getting that place and staying there is crucial.
"If I can string five games together, then we'll see what happens."
