Whats so odd about it?
Argentina will win the group with just a tie.
A loss would put them in potential trouble only if S.Korea blows Nigeria out of the water.
Argentina is playing with "subs" (world class subs btw, i think they'll perform really well today).
A -1 line assumes that Argentina has to win by 2 goals, which is very very reasonable.
You have the group of people who think that Argentina will do really good (i include myself here)
and the group that think Greece will manage to get their much needed win to classify.
Line sounds perfect if you ask me....
