Closer to the football on every snap the less you want to play them as freshmen.
Not saying everyone because there are some rare occurrences but you can't throw kids out there to compete against grown men unless they are a lot more physically developed than their age. If they were like a Dante Stills they would already be playing.
But....with this new redshirt rule conventional football wisdom goes out the window.
This is the usual order
WRs and DBs
Then RBs and LBs
Then TEs and QBs
Then DE and OT
Then the Interior Line.
