So, I plotted my guesses into a World Cup sheet and Neymar seems a good shout at odds 11 to be topscorer of the tournament:
Pros:
- Switzerland, Costa Rica, Serbia could be around 7-8 goals for Brazil. The knockout stages could be around 9 goals if they reach the semis.
- Previous winners have played all games during the tournament
- Easy and attacking opponents: Switzerland, Costa Rica, Serbia, Mexico/Sweden, Portugal, France
- "Easy" path to the semis, where they'd be guaranteed a 3rd place match also
- "When nervous/in doubt, pass it to Neymar"
- The topscorers of previous World Cups have all been players who played full minutes every match (Griezmann could be subbed for France)
Other mentions:
- France have a high goal probability and have a VERY strong team.
- Argentina has had a bad patch in the qualification - Messi might not shine so bright.
