Colin Kaepernick looked like a new guy during warmups Friday afternoon.
He’d drop back, raise the football to his ear and fling it in one quick, compact motion — up and out. It seemed like a perfect recreation of Aaron Rodgers’ throwing motion, the ideal throwing motion.
Kaepernick used have a long, loopy motion. When he threw a football, he’d bring it down to his waist, then extend his right arm all the way back like a pitcher.
This offseason Kaepernick decided to shorten his stroke and improve his knowledge of the game.
