The position I've been most concerned with above all is at RT.
I'm not worried about Zion at LT despite him being a TF because he's a naturally country strong kid from South Carolina, a state that quietly produces some really great freak athletes on the regular (Kevin Garnett, Ray Allen, Robert Porcher, Levon Kirkland, John Abraham, AJ Green, Alshon Jeffery, DeAndre Hopkins, Jadeveon Clowney, Stephon Gilmore, Jonathan Joseph, DJ Swearinger & a bunch others, and of course most recently Zion Williamson & Ja Morant. Even right now for the 2020 class the #1 ranked player in the nation is a DE from South Carolina.)
The point being, Zion Nelson imo is a kid that will maturate into the LT spot & will develop into a legit full time starter due to his natural ability & rapid wildfire growth. He's shown he can move & does a good job engaging with pass rushers & can anchor.
Herbert on the other hand is the one I'm not so confident about. His footwork vs speed rushers has always needed serious work. He does well in the run game when he has to move forward & get to the 2nd level of the defense, it's his pass protection that will be the big question mark.
I'm gonna trust that Coach Barry obviously chose him at that spot because he's seen enough from him to feel he fits best there & hope he's improved his technique.
I've always felt Scaife projects best at Guard but is also good enough to be a very good Tackle as well. If need be, I think we could move him to RT if Herbert struggles, but we'll have to see how it works out.
As of now, I'm just hoping we have a steady 5 that has built continuity & will be enough to hold up throughout the season. We've played musical chairs on the OL for too many years as of recent & that's the one area of this team that we must get right if we ever plan on turning this thing around & become a contending team.
