France was probably overrated heading into this tournament.
Last year in Eurobasket, they went 3-2 in the group stage including a 13 point loss to Germany.
They won in Overtime in two finals - the round of 16, and again in the quarter final (Turkey and Italy).
Lost the final by 12 to Spain, and the only time they led was 1-0. Spain got out to a 20+ lead, France got it back to 3 early in the 3rd before Spain kicked away again and won comfortably.
France came into the WC missing their starting PG Heurtel who averaged 10 and 7 (banned because he plays in Russia). Their main guys are all in their 30's and a year older (Batum, De Colo, Gobert, Fournier).
Looking at it now, I'm not sure why they were such favourites.
Plus they got another group of death, like Australia did. Latvia is good. If there's a Euro team in the world cup, I operate under the assumption they're probably pretty decent and capable of beating anyone on their day, and that certainly seems to be the case here.
