49ers guard Jonathan Cooper aims to trade pain for productivity Posted Aug 18, 2018 San Francisco 49ers guard Jonathan Cooper has been benched, traded, released and injured. His injuries help explain why despite being the No. 7 pick out of UNC in the 2013 draft — Cooper was the highest drafted guard in 27 years — he’s been with five NFL teams in the past 29 months. And they also explain why he needed little prompting to discuss his health in a recent interview. (San Francisco Chronicle)
