Not anymore. Friday's trade with the Baltimore Ravens for 24-year-old offensive tackle Orlando Brown Jr. filled the vacancy left by Fisher on the blind side, providing the cherry on top for a sneaky-awesome offensive line rebuild. The Chiefs also added mega-efficient, durable and reliable veteran Joe Thuney at left guard. They brought three-time Pro Bowler Kyle Long out of retirement. They signed the versatile and battle-tested Austin Blythe as a potential replacement for Reiter. And they re-signed veteran Mike Remmers to return—ideally—as a swing tackle/depth piece. Throw in the presence of Andrew Wylie, Martinas Rankin, Nick Allegretti and 2020 opt-outs Duvernay-Tardif and Lucas Niang, and just like that you've got one of the deepest offensive lines in the NFL.
