May 2, 2021 The Dallas Cowboys used all of their selections on Day 3 of the 2021 NFL Draft on Saturday. Below we have an instant grade on each pick, along with links to our Cowboys SI Draft coverage and links to NFL Draft Bible bios on nearly every player. Round 4 NFL Draft Bible Scouting Overview: A mainstay for the national champion Bison for three seasons, Cox made the most of his opportunity with LSU in 2020. A long, athletic linebacker who exhibits tremendous range and athleticism, Cox was a major part of three FCS national championships at North Dakota State. He boasted excellent stats while there with 258 tackles, 32 tackles for loss and 14 sacks. With the impact he showed at LSU, his traits were shown to be able to transcend any competition level. He is a dominant sideline-to-sideline linebacker who can also rush the passer. Cox has outstanding coverage ability, in both man and zone. He was one of the best players in the FCS during his tenure at NDSU, and quickly became not only one of the more talented defenders in the SEC, but in all of college football in 2020. With the competition question marks put to rest and another nice showing in Mobile at the Senior Bowl, expect to hear Cox’s name somewhere on Day 2 with the type of talent to become one of the better coverage linebackers in the entire league.
