Colin Kaepernick will enter the quarterback free-agent waters today when he officially opts out of his contract in San Francisco.
That makes him an option for a Cleveland Browns team that needs to consider all options.
Kaepernick is 29, a former second-round pick out of Nevada. His career passer rating is 88.9 and Total QBR is 64.9.
His overall statistics put him in the middle of the pack among NFL quarterbacks in his career. His accuracy is not great, and he's been sacked way too often — 171 times, which ranks 14th-highest during his NFL years.
