"It was about 16 years ago in Saint Joseph's gym in Philadelphia, where a talented high school player first met an assistant coach for the Philadelphia 76ers." (Source: Chicago Bulls coach Tom Thibodeau recalls first meeting Los Angeles Lakers star Kobe Bryant - ESPN Chicago)
Why is there a comma after "where"? What follows "Philadelphia" seems to be a restrictive clause. Also, the sentence would sound better to me if "where" were replaced with "that."
What do you think?
