what is Bettis implying here?

from this article link

he says [ QUOTE ]
"For some reason, Coach would never really commit fully to Kordell ... and because of that, we had no consistent leadership from the quarterback position," Bettis wrote.

"Nothing against Tommy (Maddox, who replaced Stewart in the third game of 2002), but I always had my doubts that he won the job fair and square."

[/ QUOTE ]

is he saying race played a factor?
