"That's a great team we lost to. It just wasn't our day"

Jack Anderson's quote suggests that the group he was playing against was a powerful challenger which his team was not able to come out on top. It suggests that the other team transcended in some method, which his team was simply not able to match their level of play. The quote likewise suggests that the outcome of the video game was not due to any absence of effort or skill on his group's part, however rather that it just wasn't their day. This might mean that the other group was simply luckier, or that the conditions of the video game were not in his group's favor. Ultimately, the quote recommends that his team was unable to win the video game, however that they still appreciated the other group for their ability and effort.
