DonDiego is pleased to have educated Kevin Lewis that all NFL owners are wealthy.
DonDiego questions whether "systematic racism is a salient feature of rich old white folks". DonDiego opines everybody is an individual; individuals - even rich old white folks - are capable of holding individual opinions.
And DonDiego opines that even if "systemic racism were a salient feature of rich old white folks" Kevin Lewis has not provided sufficient evidence that NFL owners are overwhelmingly racist.
At the commencement of the 2014 NFL Season (the latest data available) 68 percent of NFL Players were African-American. Ref: heavy.com
DonDiego opines that Kevin Lewis has not made a case that racism is the reason Mr. Kaepernik remains unemployed.
DonDiego suggests that the return of Mr. Kaepernik to the NFL would not be economically beneficial to the NFL.
Oh, . . . and at least one sports journalist offers another conclusion not related to racism:
"From the perspective of NFL owners, here's what all of this means regarding Kaepernick: They don't like that national anthem thing, but they could get over that in a hurry (see Reid). They believe the now 31-year-old quarterback who took the 49ers to two NFC Championship Games and a Super Bowl is closer at this point of his career to Rice (can't play anymore) than to Hunt and Reid (capable of adding more billions to the league's billions)."

. . . makes sense to poor old DonDiego.
Oh, . . . and there's this possibility:
"If all you have is a hammer, everything looks like a nail."
"If all you have is a hatred of wealthy old white men, everything looks like racism."
