Horn starts day one.
The only other 2021 starter I'd bet on would be Christensen at LT or LG after the bye week
Several of the other draft picks will rotate in often during 2020 ( Marshall, Tremble, Hubbard, Nixon). And maybe Deonte Brown gets some work in the jumbo OL packages.
I think the real benefit for this draft class will be seen in 2022 when a few veteran contracts will end and some of these rotation rookies will be able to challenge for starting roles.
