Miles Craigwell joined @irbsevens, for the second live Twitter chat of the 2011/12 HSBC Sevens World Series, from the team hotel in Las Vegas.

The former American football player who crossed over to Rugby Sevens two years ago spent 30 minutes responding to fans questions from around the world ahead of this weekend's USA Sevens.

Following a disappointing campaign last weekend at the Hertz Sevens in Wellington, USA face matches with Canada, Fiji and Argentina in Pool B at the Sam Boyd Stadium, looking for an improved performance. 

"We have to be competitive with all teams," said Craigwell in response to one question.

"We have to be in order to take rugby to the next level in the USA."

Since crossing over Craigwell has since made himself a regular in Al Caravelli's national team based at the Olympic Training Centre in Chula Vista.

And one fan posed a question about whether or not he was aiming to be a part of the Olympics in 2016.

"That's the aim," added Craigwell.

"Lord willing my body stays fit and in shape. Only time will tell."
