Edmonton Oilers superstars Connor McDavid and Leon Draisaitl made an appearance at a beer league hockey game at Newmarket, Ontario. However, reports that the dynamic duo were held off the scoresheet have left NHL insider Frank Seravalli skeptical.On the NHL Insider Notebook, Seravalli shared his thoughts on the unexpected beer league outing."First off, thank God I wasn't on the other end of that because that would certainly strike the fear of God into me going up against those two guys and how well they skate in any sort of beer league appearance," Seravalli said. (18:30)Seravalli appreciated how, on an ordinary weeknight, two of the best players in the world showed up at a local rink in Toronto. People came in just to watch them, and word spread quickly through on social media.Still, for anyone on those teams, getting the chance to play with or against those stars had to be the thrill of a lifetime, noted Seravalli. Despite reports of Connor McDavid and Draisaitl being held to zero points in a 6-2 loss, Seravalli questioned the accuracy of the information."So, uh, pretty awesome to see. And yeah, I don't I don't know about the reporting. Were those scores accurate? Were they really held off the board? Maybe they were just out there having fun."He went on to suggest that the duo might have simply been out there "having fun" rather than trying to dominate the game.Beer League referees awestruck by Connor McDavid and Leon Draisaitl's appearanceIt's not every day that beer league hockey players get to share the ice with NHL superstars.
