Pass rushing once was a skill. In today’s NFL, it has become a position
It's just the game evolving and adapting. The NFL and college games are QB focused now and being able to put pressure on them is one of the most important aspects of defenses now.
There's been a lull it seems the past few years on the value of bookend LTs and I can see that changing in the coming years with the glut of premier pass rushers that are in the league at the moment.
