4-8 points at the deadline, with the 2 week (?) break, that's a lot fewer games than it seems. I'm not saying they'll be there at the end, but by March 7 there are only 11 games. Of those, only 3 are strong playoff teams. Rest are either wild card or below. That includes one against Calgary that's almost a must win to be in that range. Ducks COULD win 5 of those 11 and stay within striking distance of the final spot by the deadline.
Likely a loss: Dallas, LA, Edmonton (though we've played them tough this season)
Tough: Detroit and Boston
Potential win: Calgary, Montreal, Buffalo, Vancouver x2, Chicago
I put Calgary in the potential because that's close to a must win to be that close at the deadline, but they should probably be with Detroit and Boston. Calgary has 12 games before the deadline, 7 against strong teams (assuming you consider Avs strong) and 1 tough game (Detroit). Lots of other variables, like the other teams in between (Canucks being one and we have 2 against them), but it's possible to be in single digits of a playoff spot in just over a month from now.
