The Chiefs were a top 5 offense in 2017 with Alex Smith. Smith had like over 4K yards passing with 26 TDs and only 5 interceptions.
His record was 50-26 as the Chief's Starter. I always felt like he was grossly underappreciated in the NFL.
He obviously was never the same player after the leg broke in 2018, and it's a miracle he even survived and still has the leg.
