In a division where every victory should be hard earned, Páidí Ó Sé will never pick up two easier points. Totally dominant from start to finish, Kerry won here pulling up.
The signs looked ominous for Roscommon in the opening minutes as Declan Quill and Colm Cooper won possession far too easily in the full forward line, helped by excellent service they got from midfielders Donal Daly and Darragh Ó Sé who were totally dominant throughout.
Quill and Cooper dovetailed beautifully, and while the Dr Crokes man failed to get on the scoresheet, he created numerous chances for Quill who took them in style to finish the game with a tally of 2-4, 2-3 from play.
Another plus for Ó Sé and his fellow selectors was the performance of Diarmuid Murphy who did extremely well in his first outing between the posts making two superb saves to deny Roscommon badly needed goals.
Understandably Ó Sé was upbeat at winning the game, principally because of the way the players had bounced back from the Cork game.
"It was one of those days when nothing went right for Roscommon, but credit to our lads, they got stuck in from the start and there was never any doubt about the outcome after the opening quarter", he said. "This win will be good for morale as we turn our attention to the Galway match next Sunday. That's going to be another big one for us, as they usually lift their game when it comes to playing Kerry.
"What happened in Cork last week was possibly a blessing in disguise. It certainly blew away the cobwebs and I would like to think the players got the message loud and clear," he said.
Roscommon offered little resistance. The defence allowed the home forwards far too much latitude and were punished severely for it. Their ball handling was dreadful while their kicking was equally bad so that they could only manage one point for 37 minutes play in the second half.
To compound their problems the ploy of only playing two players in the full forward line backfired badly for the visitors and the Kerry defence with captain Barry O'Shea excellent at full-back after a shaky start, and Seamus Moynihan totally dominant at centre back, were completely on top.
Roscommon coach Tommy Carr tried to put a brave face on the defeat, but agreed that, on the day, his charges lacked the tools for the job.
"I feared a Kerry backlash and that's exactly what happened. We needed to get a couple of early scores and didn't.
"We hit their keeper a couple of times with the ball dropping short, had six wides and that sapped our confidence"
Carr said his side got a big lesson in ball handling skills and speed of thought: "I don't believe there is 12/13 points between the quality of the teams in the first division. It was an expensive lesson for us and what matters to me is how we react to it".
Asked if his charges can pick up the pieces for the visit of Cork next Sunday, Carr said Gaelic footballers are very resilient people and it will be a huge test of character.
"We are being asked a question now. Today's defeat has hurt. All the lads are very down, frustrated and angry at the way the game went, but I'm confident things will be different in Hyde Park next Sunday."
Dara Ó Cinnéide's excellent freetaking edged Kerry 0-3 to 0-1 in front after 10 minutes before Quill had the first of his two goals eight minutes later.
In a marvellous four man move, Cooper put the O'Rahillys man clean through and he made no mistake from 12 metres out.
Kerry were rampant and after Nigel Dineen the only Roscommon forward to pose any real threat blazed over the bar with the goal at his mercy, Quill struck a second time following another sweeping move, which put the home side 2-5 to 0-3 in front at the short whistle.
