This may be a minor thing but it’s something that could end up being a small factor in a few Detroit Lions games this year: Detroit could have a fairly mean 2 TE set with Brandon Pettigrew (almost recovered from injury) and offseason acquisition TE Tony Scheffler. Scheffler is a good player. A few years ago, he was a great option for Jay Cutler in Denver when Brandon Marshall and Eddie Royal were covered. Similarly in Detroit, Scheffler may find some good space to get open in the middle and sit in zones especially, using his size to block out some space. Calvin Johnson will be the primary focus of most pass defenses and that automatically opens up at least a bit of space for Scheffler/Pettigrew. Also, Pettigrew himself was starting to look pretty good last year before his injury.
Now, I still think the Detroit D will struggle. Vanden Bosch, Corey Williams and Suh may all add some teeth to the D-Line, and Louis Delmas is a very good safety, but it won’t be enough and the D will likely continue to struggle.
