They charted the number of "comments perceived as bias" over the course of one game. Surprising no one, Chicago White Sox's Hawk Harrelson and Steve Stone carried the torch with 104 biased comments DURING ONE GAME. The next closest was the Indians duo who made 23. Meanwhile, our hometown pairing of Dick 'N Bert finished tied for sixth-most biased comments with nine (with one such example being "I hope there's no suspense. A nice, methodical win would be nice.").
In regards to why this phenomenon happens, Dick Bremer said:
"Former players have tremendous equity in the franchise they played for. From their perspective, I could imagine a strong desire for the team to do well."
While it makes sense in the case of Blyleven but Harrelson, who played in the majors for quite some time, never suited up for the White Sox.
