How to pick Starters? Need Experienced Help!

Hey All -
I’m new to this whole shebang. I’d like to learn how to pick starters without relying on rankings. I think, after listening to every podcast, that the one takeaway is the following: “Follow the work”

That being said - is it a good rule of thumb to look at
1.) Rush / Target attempts
then if its comprable to others
2.) Efficiency with that work
then if its comprable to the other
3.) Matchup
Is this a good way to go about things?
