The disparity could hardly be greater but Darren Sweetnam insists there is no danger that Ireland will take their eye off the ball when the USA Eagles land in Dublin on Saturday.
After last week's win over the world number one side, New Zealand, Joe Schmidt's side host an American team unbeaten in Tests this season – a run that includes wins over three of Ireland's World Cup pool opponents – Scotland, Russia and Samoa.
Sweetnam, who will win his third cap, told RTE Sport that watching the win over the All Blacks only heightened his desire to pull on the green shirt.
"Ah stop, I watched it at home with my girlfriend but after watching that you just really want to play, you want to be out there," the former Cork hurler said.
"I just can't wait for the opportunity now on Saturday."
Sweetnam insisted that Ireland, who have made 14 changes to the team from last weekend, have done their homework, fully realising that it's a game that Gary Gold's side, ranked 13th in the world, have probably targeted in the knowledge that they would face a largely second-string selection.
"With every team we have a massive look at them and their individuals," the 25-year-old Cork Con man said.
"They have a lot of good players, like their 12, Paul Lasike [Harlequins], your man Cam Dolan, the number 8, even [captain] Blaine Scully [Cardiff], we would have played against him in the Pro14.
"John Quill [wing forward], I used to play with him back in Dolphin back in the day.
"They have a lot of good players and a lot of strong ball-carriers so they are going to be good and they are going to be up for it.
"Whoever we're playing, we are going to be ready for it. It's an opportunity for guys so we're going to be fired up as well. It's going to be a big game and we're really looking forward to it."
