Head Coach #5: Frank Reich (2020): 11-6 with Philip Rivers starting

Offensive Coordinator: Nick Sirianni (2020)

When Philip Rivers signed with the Colts after the Chargers didn't re-sign him in the 2020 offseason, Charger fans knew that it would look strange to see him in another uniform. But this team ended up fitting him perfectly.

Rivers got to reunite with former Chargers OC and QB coach Frank Reich, and as you've seen from the Mike McCoy era slide, these two obviously have a lot of chemistry together.

In what ended up being his final year in the NFL, we got to see Rivers play in a system that fit him really well. Rivers played with a consistent running game and an offensive line that, other than the brief stint in 2018, he hadn't played with in over a decade.

Rivers had a solid season and proved he could still do it, throwing for 4169 yards and 24 touchdowns while completing 67% of his passes. He threw for over 4000 yards for the eighth consecutive season, and for the 12th time in the last 13 seasons. Rivers led the Colts to some big wins, including beating the Packers in overtime (the second year in a row that Rivers beat the Packers), beating the Titans on Thursday Night Football, and going on the road to knock the Raiders out of playoff contention while keeping the Colts playoff chances alive.

Rivers led the Colts to an 11-5 record, but like in 2018, were a wildcard because they lost the tiebreaker against their division rival. The Colts wildcard round loss in Buffalo ended up being the final game of Rivers' career, as he officially retired from the NFL on January 20th, 2021.

Offensive stats under Reich (2020): 56% pass plays, 44% run plays, Pass yards rank: 10th, Rush yards rank: 14th, PPG rank: 9th
