You say that Rooney and Hernandez did score, and so you can say they won us the league, so why can't we apply the points you laid out here:
to them as well?
Go for it, do it but let's be honest, those points against the teams I mentioned at that time of the season whilst literally equating to the same amount mean more in terms of significance, and you damn well know it.
The fans know it, the team knows it, the media knows it. I'm not sure if it was you but already had this discussion, three points against Chelsea in April mean more than three against Blackburn in December and Berbatov has shown he's incapable of scoring in these title important games...
