Sesay is friggen stud. He's 100% a take and he's among the most coveted edge rushers in this cycle.
That said, this is the reason the likes of Alabama, Georgia and Clemson stack(ed) talent not only in each class, but cycle-after-cycle as well. If you miss on one guy that doesn't develop as you expected he would, it's simply a matter of "next guy up". You take as many high end talents (regardless of rankings) as you can, maximizing your chance of hitting and building out competition within the position room and a quality 2 or 3 deep for game day.
