Well apart from that obviously not being a straight comparison it does obviously show Billy scores goals. Don't think anyone can deny that, it's fact.
I'd also argue he's not effective for every situation. He's not brilliant at every aspect, nor should he be. He's very effective when were good, positive and creating the chances he thrives on. The reality is were often not at that level and in those situations we need a striker who can create something from nothing. Someone with pace would be very useful. That's not Billy unfortunately.
I'm not slagging him, if we had the team of say Fulham last year. I'd play Billy week in week out and watch him bang em in every match.
