Cavan's poor league form under Graham continued in 2021, ending with relegation to Division 4 after a defeat to Wicklow.[31] Tyrone brought an end to Cavan's reign as Ulster champions in the first round.[32]
In 2022, Graham led Cavan to promotion from Division 4 at the first time of asking,[33] and also won the league final by beating Tipperary.[34] After exiting the Ulster championship to Donegal,[35] Graham managed Cavan to the inaugural final of the Tailteann Cup against Westmeath.[36] Westmeath were winners by a four-point margin.[37] On 8 August 2022, it was announced that Graham would remain manager of Cavan for another two years.[38]
Graham managed Cavan to a second consecutive promotion in 2023,[39] and Cavan also claimed a second consecutive league title with a win over Fermanagh in the final.[40] On 10 July 2023, Graham stepped down as Cavan manager after five seasons of managing the team.[41]
