HBA would've certainly made a difference. Direct wingers of his ilk are an absolute necessity in our current set up because we don't coach a team game, we need his sort that can rise above the lack team strategy and just do things on their own (even if it's once every 5 games). Invariably, these sorts of lads tend to cost a lot of money, though, so we've shot ourselves in the foot.
I do think he lost a little something after his 12/13 injury, but he'd have still made a difference.
