On the back of one game, albeit an All-Ireland final, so much can change.

There are those who are suggesting that Dublin have slipped slightly on the back of last Sunday's draw with Kerry.  

How much of that, however, is down to the intensity and physicality that Peter Keane's side brought to proceedings. Quite a bit you would have to say. The sending off of Jonny Cooper was also a factor.

Of course, there was all the talk beforehand of Dublin creating history, with the five-in-a-row. Did that seep into the minds of the players?  

Perhaps, even more telling was the fact that two years has passed since Dublin last played a championship match of real intensity. Gavin's side were again pushed all the way by a Mayo outfit on final day in securing the 2017 All-Ireland crown.

And then there is the Dublin defence. Kerry had enough chances to make more of an indent on the scoreboard in the drawn game. Indeed, the Munster side have been accused of putting the handbrake on too soon in their efforts to win a first All-Ireland in five years.

A point up after 64 minutes and with momentum on their side, the ability to drive it home was not forthcoming. Credit, however, must go to Dublin for the ferociousness of their play in those final minutes as their rivals failed to make inroads towards Hill 16.

At the end of it all was a stalemate in a contest that was compelling, while lacking what you would call real quality.

A lot of very good footballers did not hit the heights last Sunday. Aside from Stephen Cluxton, Brian Howard, Dean Rock and Jack McCaffrey, who else on the Dublin team can say they were happy with their afternoon's work? Kerry will feel that there is more to come from the likes of Stephen O'Brien, David Clifford and Paul Geaney. 

Another day out out to show your true worth and the potential of a blockbuster to end a reasonable football year.

As for the game itself, many questions abound as to who will learn the most and what changes there will be in team selection?

Kerry, perhaps, are more likely to start with the same XV and there's a chance that James O'Donoghue could be fit enough to make the squad. Dublin may be forced into the changes following an injury to John Small, with talk that Eoin Murchin could start after limited appearances so far this season. Will Bernard Brogan have his swansong by making it back onto the panel?

Speaking on RTÉ Radio's Saturday Sport, Oisin McConville, believes that "Dublin are now fallible and can be got at in certain areas" following last Sunday's clash.

Yet, he added:"Nine times out of ten, the team that you expect to win the first game (Dublin) will come back and learn a little bit more.

"When they look back at the video, will feel there are a lot of areas they can improve on. You look at Jim Gavin's decision to persist with Jonny Cooper on David Clifford even after the first yellow. I get the sense that Gavin does not trust his defence in the same way he used to."

When pushed on what the outcome will be in the replay, the Armagh All-Ireland winner still feels Dublin, on the back of their greater big-game experience, will prevail, but only after a titanic battle against a Kerry side who will have "learned an awful lot" from the last day.

Such learnings and the fact that Kerry matched up to Dublin in the physical stakes a week ago, alongside a few former Kingdom players talking up their chances, underlines the confidence within the camp that they can take down the Dubs.

Kerry halted Dublin's drive for a fifth consecutive league title in 2017. Halting a much bigger push on an autumn Saturday would no doubt give them greater satisfaction. They will go in as underdogs and replays as a rule don't tend to favour those longer in the betting.

But Kerry, in the words of Peter Keane, Kerry are not "coming up for the spin".

The time to deliver is now.
