McGinley will captain Europe against USA at Gleneagles next year in golf's ultimate team event, but had a watching brief in France as 10 British and Irish players combatted a group of their peers from the continent.
Jose Maria Olazabal's Europe edged Sam Torrance's British and Irish side 15-13 over a thrilling week of matchplay to end a run of six straight defeats in the Seve Trophy, with Francesco Molinari sinking the winning putt.
However, McGinley reckons all 20 golfers on display will benefit from their involvement in a team competition - and expects some of the men never to have teed off in a Ryder Cup to be part of his squad in Scotland in 2014.
"It was a great week for me as a neutral and I have seen and learned a lot, while it has been a great learning curve for future Ryder Cup players, too," explained the Dubliner at the culmination of the Seve Trophy.
"The experiences they have had playing under two experienced captains are going to stand them in really good stead and help them perform if they make it into the team next year."
McGinley, a non-playing skipper at the Seve Trophy in 2009 and 2011, continued: "It has been evident this week that the players are really up for it and I love seeing that spice and fire.
"I expect, and will welcome, rookies into my team and I will not discount the possibility of picking a rookie because I understand how good these players are and the strength of the European Tour."
France's Gregory Bourdy - who won the Wales Open at Celtic Manor in September - made Seve Trophy history by winning all five of his matches, four of them whilst partnered by Joost Luiten.
McGinley was impressed by the 31-year-old's game but also enjoyed getting to know how Bourdy ticks off the course, something he says is vital as the race for places at Gleneagles hots up.
"You look at all the great players than have played in the Seve - Seve Ballesteros, Ollie [Olazabal], Ian Poulter, Padraig Harrington, Colin Montgomerie - and none of them have won five out of five, so all credit to him," McGinley added of Bourdy.
"I didn't know him very well, but have spoken to him this week about French wines - which he loves - and I have been with Nicolas Colsaerts, too.
"That has allowed me to get an overall impression of players' personalities and not just their golf, which is important."
