This is correct. Every position is not ranked equally. OL is critical.
Rank them. I'll let you know if you are correct.
Very rough, but for me:
1. QB. We are fortunate, we have the best young QB in the NFL. Drake Maye is the most valuable property in the NFL.
2a. OL. You have to protect the
QB, give him time, keep him upright, keep him healthy. OT > IOL, but the OL needs to operate as a unit.
2b. DL, both IDL and EDGE. You need to put pressure on the other team's QB, and stop the run. Internal pressure more difficult to counter than outside pressure.
3. Secondary. Outside CB > nickel and S, but the unit needs to work well at all levels.
4. TEs. Force multipliers and Queens on the chessboard.
5. WRs.
6. LBs.
7. RBs.
I am not diminishing any unit. Good or great LBs can be the glue that makes a great defense, and versatile RBs who can rush, catch and block are almost as valuable as a true Y-TE. But generally, 1-3 are the units that can dominate to the point of winning a SB, especially when you have more than one of those 4.
Connecting this to the OP, my goal is not to plug a hole at RG. It is to build the most talented, athletic, versatile and deepest OL in the NFL to protect and optimize the ability of the most valuable commodity in the NFL: Drake Maye. That requires more than just a mid-round investment in an adequate RG.
RG is often considered the least important position on the OL and the easiest to fill, but many teams have put their best lineman there, including 1st round picks like David DeCastro and Quinton Nelson. I want the equivalent of 2 healthy AVTs at LG and RG.
