The Pittsburgh Steelers have a defense which is riddled with Day 1 and 2 draft picks. Just look at the list of players who were drafted in Rounds 1-3 in their respective draft classes:
Cam Heyward
Stephon Tuitt
Minkah Fitzpatrick
Terrell Edmunds
T.J. Watt
Alex Highsmith
Joe Haden
Devin Bush
Tyson Alualu
Cam Sutton
Justin Layne
That is quite the list. Now, if you go to the offensive side of the ball, the list is much smaller.
Ben Roethlisberger
David DeCastro
James Washington
JuJu Smith-Schuster
Chase Claypool
Diontae Johnson
Chukwuma Okorafor
Eric Ebron
Now, not all of the aforementioned players have been drafted by the Steelers, like Haden and Alualu, but the defensive side of the ball has seemingly be the focus of the team for the past several seasons.
