Colin Kaepernick has offered to join the New York Jets practice squad in a letter addressed to the team’s general manager, Joe Douglas. Kaepernick wrote that he wanted to help the team prepare for mobile quarterbacks and expressed his belief that the opportunity would give the team a clearer look at his skills. The Jets have yet to respond to Kaepernick’s offer, but they are expected to make a decision soon as they look to fill the void left by Aaron Rodgers’ injury.
