Nigeria struggled at the last World Cup and against Burkina Faso, Bosnia will have a similar desire to win in their first appearance on the big stage. That said, I am sceptical about African football in general so I'll try not to judge them beforehand too much. Key point though, for any of the the two teams to qualify from that group is that they're next to France, the great seeded team of Switzerland, and god knows what else, so that's definitely an opportunistic area of the draw.
As for the group of death argument, you can't call out Chile as a one-man team (they at least are a two-man one, with Sanchez and Vidal) when Group G contains Portugal.
