A wild card team to have an eye on are the Calgary Flames. The team doesn't have a Mcdavid, but they have Johnny Gaudreau (scored up 80 points in 2015/2016), Sean Monahan (averaged around 60 points for the last three years), then upcoming stars Michael Ferland and Matthew Tkachuk, along with a great defensive lineup with Giordano, Brodie, Hamilton, Stone and Hamonic.
If Mike Smith can be fairly consistent for the team in net, I'm seeing the potential for a deep playoff run. Maybe like Ottawa this season with Craig Andersson. Patrick Roy, Dwayne Roloson and Tim Thomas had some of their best seasons past 35 years as well, so I think Smith has the potential to do well.
