Things you come to expect from Jim Gavin as Dublin manager in a championship game.
An early second half substitute - he has never not made a tactical personnel switch before the 45th minute.
An exhausted bench - from 2013 when the limit of substitutes was five to last year when it was raised to six with the arrival of the black card Gavin has never failed to use his full complement of reserves.
The same faces, the same places - in all but one their four games this summer, the replacements have been two in defence, one in midfield and three in the forward line.
That is generally the case for most teams but then Dublin have the same men entering the fray each time - Alan Brogan and Mick Fitzsimons have come on in all four.
Bar the one he started, Paddy Andrews has appeared as a substitute each time.
While Kerry have used 26 players this summer, only three players seeing every minute of their five games, according to GAA statistician Rob Carroll Dublin have used 25.
Just three have been involved in their four matches from start to finish - Stephen Cluxton, Jack McCaffrey and Brian Fenton.
But unlike Kerry there has been no need for horses for courses.
Dublin have made personnel changes purely on the basis of form and injury. Michael Darragh Macauley and Denis Bastick have taken turns in partnering Fenton largely because Macauley’s form has been so erratic .
Eamonn Fitzmaurice may be complimented for his ruthlessness but Gavin has shown over his three seasons in charge that he has a short fuse when it comes to tolerating under-performing players. Across the 15 games, he has made 11 half-time substitutes.
Gavin doesn’t overhaul his teams to the extent that Fitzmaurice does - his team on Sunday shouldn’t be too far removed from the one that face Longford in May whereas Kerry against Tyrone showed five changes from the Tipperary game in June - but his voice is just as clear: shape up or you’ll be shipped off.
