The only person who wins every round they fight is Father Time. The Pittsburgh Steelers have been fortunate for years to have great talent along the defensive line in Cameron Heyward, Stephon Tuitt, and Tyson Alualu, but they know the time will come for them to move on with their lives. Both Alualu and Heyward are already in their 30s.
While it’s impractical to expect to replace them with equivalent talents, the next-best thing the Steelers can do is bring in players now who can learn from the likes of Heyward and Alualu before it is their time to take over.
