Maris did not know who Mia Hamm is - so I helped him by describing her as the Sergio of Futabol. Unfortunately, it seems that Mia might have never been, as shown by Mr. Evans.
Why do we care that Tyreke Evans can't remember Sergio Rodriguez? He never played for the Blazers right?
You missed the joke. He was pretending that he couldn't remember Sergio playing here, just like Evans couldn't remember him playing there.
Seems to be the interviewer's poor English that caused the confusion (he can't pronounce Sergio), then the video is abruptly cut off before things are clarified and Tyreke speaks wistfully of the Maloof's folly (trading Sergio) as they refer to it in Sacramento and how it ultimately cost the city their team.
