Furthermore, UEFA decides which teams get seeded using that same coefficient system. Each team has a coefficient based on that individual team's past record in the UEFA tournaments.
Meanwhile CONCACrap gives seedings out based on perceived national successes. So in theory, Orlando, could win the US Open Cup and automatically get seeded for the group stages. Meanwhile if TFC wins the Canadian Championship, they will be given a harder group because it's a Canadian team, despite making it to the semi finals.
If QPR were to win the EPL, they would still be seeded lower than the other English teams due to QPR's lack of recent European experiences.
