Just about a month of the 2018-19 NHL campaign is in the books, and there have been a number of surprises on both ends of the spectrum in terms of early-season standings.

The defending Stanley Cup champion Washington Capitals are off to a so-so start, opening 5-4-2 despite plenty of goal production. Overlooked franchises like the Montreal Canadiens and New York Islanders have exploded out of the gate with top-10 goal-differential marks and winning streaks. And anticipated postseason contenders like the St. Louis Blues and Vegas Golden Knights have been wrought with inconsistency, starting a combined 9-11-4.

Preseason darlings like the Tampa Bay Lightning and Toronto Maple Leafs have hardly crumbled under the weight of pressure, meanwhile, flashing elite offense to rank among the league's best after October.

November, of course, is still an early month to judge an NHL team's season, but at the very least, we've now got a couple weeks worth of material to make judgments. And it's a little easier to project which contenders just might have the strength to go the distance.

According to Bovada's latest Stanley Cup odds, most of the familiar foes atop the standings remain the favorites to take this year's championship. But a month of the 2018-19 season has dictated quite a bit of movement among others. All of Bovada's top four Cup contenders, for instance, have improved odds since the start of the season, but long-shot picks like the Canadiens, Colorado Avalanche, Carolina Hurricanes, Philadelphia Flyers, Los Angeles Kings and Detroit Red Wings have seen dramatic changes.
