Just by looking at the H2H and recent games, they didn't seem like -2.5 Handicap team for Canada, it was an easy decision...
On the Tennis question, I think the question should be null and avoid, how can some not playing in a tournament get eliminated, and I did research on the tournament after not finding him on the bracket, and I'm sure there was a link that mentioned that he would join the tournament from a specific round or so.
I experienced the same problems. I looked up the bracket and schedules on many livescores but couldn't find Alex De Minaur fixtures but I just went ahead and picked him because of his seed ranking and since I don't know much about tennis fixtures and stuff like that but if the question was set on purpose only the Cro2 team can clear that up, I also noticed that the Cro2 team went the other way round just like the majority of the members, there could have been a mix up somewhere and I'd love to hear their explanation
For the Canada game; some.of you really thought Canada is a good football team? Fellas they only have mid players with 1 world class LB
There were two websites that I found on Google saying that De Minaur is already out. One website is a tennis discussion forum and they mentioned that on June 25th already. The other website also reported on June 25th that De Minaur is out and Jarry wins by walkover and plays against either Barrere or Ruusuvuori. That was kind of the confirmation for me that the news is real.
Edit: But I did the research at a later point in time and when I first had a look he was still scheduled.
But I actually lost the Georgia question because I waited for so long. I wanted to go with Georgia wins the group, but when the Netherlands scored that goal and I saw the game statistics, I changed my answer to runner-up - and lost! Even before the game I wanted to go with Georgia as the group leader, but this goal made me think that Georgia will be shocked and fall apart in the 2nd half. Indeed lost a point because I let myself be convinced of the wrong outcome.
