Ruiz is only 25 as well. I'm not saying Ruiz is an All-Pro and hasn't had plenty of issues at times, but again, if you can simply get decent play from those 4 that's a good start. Health obviously is key as we know all too well.
Ruiz was drafted the covid year and didn't get the benefit of a real rookie off season. That delayed his development.
