Have to agree with Caliburn on this one. I initially had the thought that; "Hey, doesn't the Copa America play way too often? Maybe it's just my imagination," but now I've got that confirmed.
Another thing is that teams like Brazil, who should easily have had 9 points in their group, and other big team like Uruguay (who have won the tournament 8 and 15 times respectively with Argentina on 14), always seems to somehow manage to fu*k up in these tournaments as of late (with the exception of last year when Uruguay won), like they don't take it seriously. Both out in the Group Stage against teams they should easily beat if they faced them in the World Cup. The only team that seems to take this cup seriously out of the big teams this year, is Argentina. Otherwise it seems like teams like Columbia as of late has been the ones that seems to go all the way.
Heck, Brazil even prioritized the Olympic Games... The OLYMPIC GAMES over Copa America. That's like prioritizing winning the Club World Cup over winning the Champions League. I mean, Neymar was only allowed to participate in either one of those two tournaments by Barca this summer, and he picked the Olympic Games over Copa America. Home turf or not, that says it all really.
