Witherspoon hopes to up his run-game defense
- San Francisco 49ers rookie cornerback Ahkello Witherspoon said he agrees with general manager John Lynch that he needs to improve his physicality against the run.
- The former Colorado Buffalo, who plans to attend medical school after his NFL career, ranked 107th in the class as a run defender — well below average.
- Witherspoon had the 156th-best tackling efficiency in the 2017 draft class and his 0.6 run-stop percentage ranked 114.
- On the plus side, Witherspoon used his 6-foot-3 frame to lead the nation in passes defensed with 13 and graded out as a top-15 cover man, which is where he will earn his paycheck.
