Colin Kaepernick hasn't visited a single team since the start of free agency and even quarterback-needy teams don't appear to be interested.

Players of Kaepernick's caliber usually get multiple shots but there are a number of factors working against him.

"He can still play at a high level," one AFC general manager said. "The problem is three things are happening with him.

"First, some teams genuinely believe that he can't play. They think he's shot. I'd put that number around 20 percent.

"Second, some teams fear the backlash from fans after getting him. They think there might be protests or [President Donald] Trump will tweet about the team. I'd say that number is around 10 percent. Then there's another 10 percent that has a mix of those feelings.

"Third, the rest genuinely hate him and can't stand what he did [kneeling for the national anthem]. They want nothing to do with him. They won't move on. They think showing no interest is a form of punishment. I think some teams also want to use Kaepernick as a cautionary tale to stop other players in the future from doing what he did."

One executive even called him "an embarrassment to football."

Kaepernick plans on standing for the national anthem this season.
