Kaepernick just isn't very good....and yet his supporters at BLM (Buy Large Mansions) insist that he's a victim.
Kaepernick's supporters remind me of Tim Tebow supporters. Neither one has what it takes to be an NFL starting quarterback but both men's supporters blame everything but their lack of talent for why they're no longer in the NFL.
As for Gruden, he was 22 and 31 over the last three years. If he was was 49 and 4 he could have said anything and he'd still be employed. But bigoted, mediocre coaches don't have long lifespans.
