They aren't skewed. RvP spent as much time in the centre in his career as Benzema did and Arsenal made it into Europe year in year out as well under Arsene Wenger. RvP's best CL record for a season are a mere 5 goals in 2008 / 2009. That's what Benzema could reach as a 21 year old kid at Lyon.
The main point here was though: Would Real Madrid trade any of their strikers for RvP? No, they wouldn't. If RvP was as highly rated as people here think ("best striker in the world") Real Madrid would surely not hesitate to get him, especially since he wants out and has 1 year left on his contract. It would be a bargain. Yet they show no interest. They DID try to get Agüero though last season. Only Atletico prevented that deal, asking for € 70 million.
Rooney, Villa, Ibrahimovic, Agüero, Tevez, Benzema, Higuain, Eto'o, Gomez, Cavani. I've just named you 10 strikers who have been as good as RvP or even better in recent years. It's rather RvP who all of a sudden is the best thing since sliced bread rather than other strikers emerging out of nowhere.
