The 49ers did make a move in the 2020 NFL Draft to reinforce the offensive line aside from Trent Williams, selecting former West Virginia offensive tackle Colton McKivitz.
McKivitz projects to be a better interior blocker at the next level, though, and he might be a season or two removed from being a proven starter. Likewise, Daniel Brunskill is a good candidate to secure a starting job at right guard, too, although it wouldn’t be a shocker to see San Francisco seek an upgrade.
Such an upgrade could also push out the veteran, Laken Tomlinson, who could be a $5 million cap casualty in 2021 with just $1.25 million in dead money.
In Round 4, the Niners may want to consider beefing up the interior of the O-line, particularly if they can target a player with plenty of upside despite some notable risks.
Alabama interior offensive lineman Landon Dickerson falls into this category. He arguably has second-round pedigree, although some collegiate injuries could force his stock value to fall a bit. The good news, though, is Dickerson is versatile and capable of playing all three interior spots, as well as doubling as a backup tackle.
