The two achievements are not unrelated: Robles' incredible consistency has made him an ever-present in the RBNY squad through the most successful period of the club's history (two Supporters' Shields, two Eastern Conference playoff finals, and a run to the CONCACAF Champions League quarterfinals...so far) and that consistency coupled with an extraordinary durability has seen him shatter the MLS record for consecutive full-games played.
Another reason he has the MLS Ironman record: he has not made much of an impact on Jurgen Klinsmann's thinking with regard to the US Men's National Team goalkeepers. Robles has won two USMNT caps in his career: one in 2009 - before Klinsi took over coaching the USA - and one in 2016, after he won the 2015 MLS Goalkeeper of the Year award.
Prior to the USMNT's friendly against New Zealand, Klinsmann mused on Bill Hamid's return to the roster and revealed his current thinking about the USA's goalkeeping depth:
When asked, Klinsmann named (in order for what it's worth): Howard, Guzan, Horvath, Yarbrough, Bingham, Rimando, Hamid, Johnson #USMNT— Seth Vertelney (@svertelney) October 10, 2016
That's eight 'keepers, and Klinsi placed Hamid at about "six or seven" on his list, per his comments to reporters at a pre-match press conference.
While some choose to debate the precise order in which the named 'keepers might be ranked, RBNY fans might prefer simply to note who isn't on Klinsi's list: Luis Robles.
The omission can be taken as a snub: Robles is unquestionably among the top tier of 'keepers in MLS, and that is a tier that Klinsmann does like to draw players from. It is also a benefit to RBNY: Robles has been able to focus almost exclusively on his club because he hasn't had his country calling on him for international duty.
At 32, Robles' career is some distance from ending - and Klinsi can always change his mind if he starts seeing something he likes about the RBNY 'keeper. But for now, it would appear the Red Bulls need not fret about any competition for Robles' services from his national team.
