In theory, a Top 5 line is gonna keep your guy protected e
Long enough for someone to eventually get open, or find a hole to pick up some yards.
Conversely, a Top 5 QB finds the plays in spite of his line sometimes. See the 2021 Bengals for a good revenge of this.
However both have their detriments. A bad QB still makes bad reads, gets picked off, can't move the ball. A bad line doesn't allow your guy to have time to make the game winning plays, again, see the 2021 bengals, last play of the SB :(
A little of both is true.
