I think Lua Lua, Buckley, Bruno and Andrews have been struggling all season. Bridcutt and Orlandi both started their problems at the start of the year.
There's definitely something odd going on. It's not just the serious injuries to the likes of Crofts, CMS and Hoskins etc which can happen to anyone but the sheer number of players who are carrying injuries and have to be nursed through the season is extraordinary-Lua Lua, Buckley, Ulloa...
