In theory you should pick the best players at the time based on ranking/Fargo or something like that. However, there is a reason for having wild cards. I am not a big fan of them, but it is what it is. Good arguments can be made that wild card picks can be used to promote/grow the sport and Duong is a prime example of this.
if you're right and it will promote growth, then fine. it's an inaugural event. but wildcard picks to me, unless going strictly by ranking, is someone that either brings something morally to the team (like shaw, like billy) that increases the team's chances to win OR someone who is much better than their ranking because of various circumstances (like biado).
