EDGE Analysis
Willis served a six-game suspension to start the 2021 season for violating the league's policy on performance-enhancing substances, but he figures to be available for Week 8 in Chicago. The defensive end appeared in seven contests a season ago, finishing with 13 tackles (seven solo) and 2.5 sacks.
