Armagh’s all-out attacking policy backfired badly against Cavan’s defensive set up 12 months ago.
Keating was one of the Cavan forwards who took full advantage to inspire a famous win.
Armagh will have home advantage for Sunday’s provincial rematch. And Keating insists the Orchard County will use the benefit of hindsight to make sure their defence isn’t torn asunder again.
Keating said: “Sure nowadays, every team is playing a sweeper, apart from maybe the Dublins and the Mayos. Armagh probably are going to play a sweeper, just to cut out that space.
“They probably will play a similar game plan to us actually, try and attack on the break. It’s just something we’re going to have to be aware of and to be one step ahead of.”
Cavan’s defensive game plan helped them to last year’s All-Ireland quarter-finals.
They reached this year’s McKenna Cup and Division 3 league finals to prove that they’re still progressing.
Keating says he’s not bothered that pundits like Joe Brolly labelled them the ‘black death’ for their style of play.
He said: “Pundits are giving out about it, that it’s not nice to watch. But at the end of the day, it’s about getting results.
“The comments don’t bother me. People are trying to get their names in the papers and trying to build a profile for themselves. Look, if they’re not talking about you, maybe that’s not a good thing either.
“But I’ve never heard any of the lads discussing it. We have more important things to be talking about.”
Cavan’s continued progress means many are tipping them for back-to-back Championship wins over Armagh.
Favouritism is new ground for a side that hasn’t won an Ulster title since 1997.
But Keating said: “I think talking about All-Irelands would be premature and it wouldn’t be realistic, you have to be realistic. But I think Ulster is very realistic for us. We’ve been building towards it. We’re going to try and get as far as we can this year.
“Last year, we only missed out on an Ulster final by a point, against Monaghan. On a different day, that could have been us going on as Ulster champions. We’re not a million miles away.”
