Carolina Panthers QB Cam Newton has been working on tweaking his throwing motion and making other changes to his routine to better his chances of remaining healthy. ‘It’s still a work in progress,’ Newton said Thursday, Aug. 1. ‘One thing I wanted to work on was just being honest with myself. Knowing when to sit out of practice and working on my body. I’m as hungry as ever. But guys that are on board on offense need me to be my best self.’
