2021 Super Bowl Champions Rams
I mean their chemistry may slightly improve. But both are in their prime, not much room for improvement. Burrow is in his second season at QB, and last year was Covid limited practices and off-season, and he was injured and rehabbing this year. Plus they always say year 3 is when you can even start to measure QB's. And Chase is a rookie. He's already put up numbers that many of the all time great WR's did in their whole rookie season. Both should be expected to be significantly better in the near future.
That connection certainly looks like they have a good future. While Kupp/Stafford connection should improve more with getting more of their timing done.
