I tried my best to find an example and I think I found one. Jacob De La Rose was drafted in 2013 (but played in Sweden in 2013-14). In 2014-15, he spent 37 games in the AHL and 33 games in the NHL. In 2015-16, he spent 34 games in the AHL and 22 games in the NHL. Then in 2016-17, he spent 62 games in the AHL but only 9 games in the NHL. Therefore, he had 10+ games in the NHL in his first two years, and 10+ games in the AHL in his final year, to lead him to being expansion eligible.
Justin Auger is another example from LA. He was drafted in 2013 as an overager and played his last season in Guelph in 2013-14. He then played 60+ games in the AHL in 2014-15, 2015-16, and 2016-17. Because he was already 20 on December 31, 2014, each of those three seasons counted as professional experience and he was exposed by LA in the Vegas expansion.
Conversely, Johnny Brodzinski finished out college and had only spent two seasons with Ontario prior to the Vegas expansion and was therefore ineligible. In fact, if we take a look at the Vegas expansion on CapFriendly (
Vegas Expansion Draft Simulator - CapFriendly - NHL Salary Caps), we can see a number of players who were exposed despite not meeting the "minimum requirements" that we've been discussing. From the Kings, Michael Mersch, Justin Auger, Andrew Crescenzi, Rob Scuderi, Zach Trotman, Vincent LoVerde, and Cameron Schilling didn't meet the NHL games played requirements but were still exposed.
Actually, let's take it even further, Vegas selected Teemu Pulkkinen from Arizona despite him having only played 9 NHL games in 2016-17 and 36 games in the NHL in 2015-16, thus not meeting the minimum requirements of 40 games played in the previous season and 70 games played over the previous seasons.
We don't have direct one-to-one comparables for guys like Clague or Strand, but suffice to say I'm 99% certain they're eligible to be selected by Seattle regardless of how many games they play in the NHL this year.
