Injuries: Le'Raven Clark (Achilles), Will Holden (ankle)
Backups: (T): Casey Tucker, Le'Raven Clark (G): Joey Hunt, (C): Joey Hunt, Danny Pinter
Fantasy Impact: After losing both LT Anthony Castonzo and QB Philip Rivers to retirement, it's a given that Indianapolis' offense will undergo a seachange by the time the 2021 campaign kicks off. A void at LT is difficult to fill, but having standouts Quenton Nelson and Branden Smith should make the transition easier. There's even been talk that Nelson could anchor the left side of the line, but considering that he's earned All-Pro honors at LG in each of his first three seasons in the league, the Colts may deem best not to fiddle with the formula.
Injuries: Jedrick Wills (ankle), Chris Hubbard (kneecap)
Backups: (T): Chris Hubbard, Kendall Lamm (G): Michael Dunn Blake Hance, (C): Nick Harris
Fantasy Impact: Cleveland went all in on bolstering the O-line last offseason, and for good reason after the unit struggled mightily in 2019. The move paid off dividends, as former Titans RT Jack Conklin immediatley became a pillar of consistency, as did 2020 No. 10 overall pick LT Jedrick Willis. The emergence of RG Wyatt Teller allowed the overall unit to become one of the league's most dominant forces, with in conjunction with an RB duo of Nick Chubb and Kareem Hunt allowed for the implementation of a lethal ground game, Overall, the stage is set for this unit to return top-5 upside again in 2021 -- especially in terms of run blocking.
Injuries: A.Q. Shipley (neck), Alex Cappa (ankle)
Backups: (T): Joe Haeg, Josh Wells (G): Aaron Stinnie (C): A.Q. Shipley
Fantasy Impact: Outstanding pass protection was a key ingredient in Tom Brady and the Buccaneers' reaching and winning Super Bowl LV, and the key figures up front stand to return in 2021. 2020 first-rounder Tristian Wirfs' already proven to be one of the league's premiere RTs, and LG Ali Marpet and C Ryan Jensen both also do excellent work in pass protection. LT Donovan Smith, for his part, is at least both durable and competent.
Injuries: David Bakhtiari (knee - ACL), Lane Taylor (knee), Simon Stepaniak (knee), Jared Veldheer (illness)
Backups: (T): Billy Turner, Elgton Jenkins (G): Lucas Patrick, Simon Stepaniak (C): Lucas Patrick, Jake Hansen
Fantasy Impact: The Packers have consistently provided league MVP Aaron Rodgers with quality protection up front for years, and 2020 was no exception, even with David Bakhtiari and Lane Taylor going down for the year. Getting Bakhtiari (perhaps the best LT in the league) and Taylor back to full health will set the stage for high-end protection again in 2021, though the timing of Bakhtiari's ACL injury could lead to his missing the start of the season. In that case, the presence of standout C Corey Linsely would still likely be enough to give Green Bay a top-10 unit.
