(From NFL.com) Walker did not start a game in his first three years with the Bulldogs, but he made an impact while playing in every contest. As a junior in 2017, he ranked second on the team with 13.5 tackles for loss and 5.5 sacks (among 40 stops) as a key reserve in all 15 games. He showed signs of a breakout in 2016, making 19 stops, 2.5 for loss, in 13 games that year. The top 100 overall recruit from Fairburn, Ga., made nine tackles as a true freshman in 13 games. Coaches finally inserted him into the starting lineup as a senior, and he led the team with 11 tackles for loss and 7.5 sacks among his 45 tackles in 13 starts.
