Tyler Seguin and Mark Scheifele had a rivalry within a rivalry. Both NHLers had a personal tradition of being the last player to leave the ice before games, and when their teams played each other, that tradition created a problem. Only one of them could stay out. They settled it the obvious way: Rock Paper Scissors.
Scheifele won the first match. Seguin skated off. In their second encounter, Seguin won by changing his throw mid-reveal — he saw Scheifele committing and adjusted his own hand before showing it. That's a late reveal, which is the most common cheat in RPS and the clearest violation of simultaneous throw rules. In a sanctioned match, the result would be replayed or forfeited. In a pre-game warmup with no referee, Seguin got the W.
Their third match went to Scheifele clean. The series was 2–1 in Scheifele's favor.
The fourth meeting, in Dallas, went to Seguin — at least according to the Stars' official social media account and the video they released. Alternate camera angles told a different story. The footage showed Seguin's throw changing after Scheifele's hand had committed. The Dallas Stars Twitter account confirmed the "result." Scheifele's expression, in the alternate footage, told you everything about what he had seen.
Taking the alternate evidence at face value, the real series is 4–0 Scheifele. Seguin has the official win from the Dallas game, but it came with the kind of asterisk that doesn't go away.
The story is a good illustration of why the simultaneous reveal rule exists. Late reveals are nearly impossible to catch without a dedicated referee watching both hands at the exact same moment. In casual games and pre-game warmups, there's nobody filling that role. The honor system holds most of the time. When it doesn't, you get a hockey player mid-reveal caught on camera from a different angle while his opponent's face falls.
Scheifele has handled the whole thing with reasonable grace. Seguin has had to live with his social media timeline having documented evidence of the fourth match available forever. The Stars' Twitter account got a story. The WRPSA got a useful case study in why officiating exists.
