There should be an edge to Galway's display given the county's subliminal irritation with the consensus that Armagh's and Tyrone's successes have redefined football.
Tyrone v Galway, Omagh, Sunday, 3.0
But what can they do practically to challenge the notion? Steeped to have qualified for this stage, Galway will welcome the opportunity to put some distance between themselves and the bizarre thrashing they got from Wexford. Otherwise the league wasn't too bad for them, with good displays from the attack.
John O'Mahony delays selection because of injury problems. He has been cursed at centre back, with a succession of his choices getting injured. Paul Clancy may start there but his aptitude is unproven. Although he's a good user of the ball, his defensive qualities are, to say the least, underdeveloped and Michael Donnellan had to switch back there to close out the result against Cavan.
The feeling in the county is that Kevin Walsh's broken toe won't have recovered and that's going to impact in a centrefield sector to which Mickey Harte welcomes back Kevin Hughes.
Tyrone have been phenomenal this season in the seamless way they have maintained standards. As energetic as ever, they are closing in on the first three-in-a-row league success in 31 years - but this would be a step above Kerry's achievement back in the 1970s because during that run, ultimately a four-in-a-row, they managed only one Munster and no All-Irelands.
Harte won't be as interested in this league unless it turns out to be part of another double and the world at large is equally focused on how effectively Tyrone's championship challenge stays on track after an exhausting 18 months.
Galway's ongoing problem in the O'Mahony years has been inconsistency. But this match demands a big performance even if the prospect of winning is dented by the injuries to Walsh, Matthew Clancy and Noel Meehan and the uncertainty at centre back.
If there's ambivalence about Galway there's none about Tyrone and they should capitalise on home advantage by progressing to another big day out.
