The game at a glance
Man of the match: Sean McCormack (Longford)Longford's win was more about the collective, but special mention must be made of the individual contributions of Dermot Brady and Paul Barden.
Points win prizes, though, and Emmet Og ace McCormack showed the way with some exemplary marksmanship both from frees and open play.
Paul Barden's clinically executed 49th-minute goal gave Longford a 1-10 to 0-8 cushion they never looked like relinquishing.
The Cavan think-tank's decision to make five changes to their defence from the line-up that started last time out against Donegal. The subbing of John McCutcheon in the 42nd minute made it a clean sweep.
Michael Duffy did a good job. He let the play flow, gave the man in possession the advantage and communicated well with the players. Cavan can have no complaints about either of the sending-offs, however inconsequential they were.
What they said
Glenn Ryan (Longford manager):
"We showed a lot of pride, hunger and willingness. The lads worked very hard and 2-16 is a great return and no fluke. The players got what they deserved for the effort they put in."
Val Andrews (Cavan co-manager):
"Longford were very, very good in the last 20 minutes and we weren't. (Brian) Kavanagh's goal made it a long last five minutes."
