Simona is the fittest and coming off the best 2013 season, he'd be my first pick at left centre. Lawrence is down on his pace and there's no point compromising both left and right centre for the sake of keeping Rowdy on the left. That said, I have little faith in Lulia, he's shown bugger all in my opinion so far. In any case, he'll have at least another week to prove himself while Lawrence is on the mend.
