Antonio Brown just unloaded on Colin Kaepernick -- saying the quarterback is "trash" on the field ... while questioning the QB's charity work "in the hood" off of it.
AB fired off the explosive comments in a sit-down interview with Naji of "Cigar Talk" ... ripping the guy for settling his past lawsuit with the NFL, saying he doesn't believe Kaepernick actually wants to play still, and openly wondering if the 34-year-old's community contributions have actually made a difference.
Brown's rant all began after he appeared to be puzzled about why people feel bad for Kaepernick these days .
