Does Colin Kaepernick want a job as a quarterback in the N.F.L.? Michael Vick said he thought a haircut would help.

“The first thing we got to get Colin to do is cut his hair,” Vick said on “Speak for Yourself” on Fox Sports 1 on Monday. “I don’t think he should represent himself in that way in terms of the hairstyle. Just go clean cut. Why not?” Kaepernick currently wears a very full Afro.

On Tuesday, Kaepernick posted a message on Twitter about Stockholm syndrome that might have been a veiled response.

“Perception and image is everything,” said Vick, a retired quarterback who rehabilitated his own career after serving time in jail for involvement in dogfighting. “I love the guy to death, but I want him to succeed on and off the field, and this has to be a start for him.”
