If Dallas goes 5-2 to finish that'll be 13-2-2 to finish the season which is crazy.
Look at their schedule. Minnesota and the Jets are the only opponents sitting in a playoff spot. 5 of their last 7 games are vs. no-hopers:
Pens (72 points, 9 back of WC2, 5-3-2 in their last 10, goaldiff -57)
Wild (89 points, in WC2, 4-4-2 in their last 10, goaldiff -11)*
Canucks (81 points, 8 back of WC2, 4-4-2, goaldiff -21)
Jets (108 points, #1 in the division, 7-3-0, goaldiff +84)
Utah (80 points, 9 back of WC2, 5-4-1, goaldiff -19)
Wings (75 points, 6 back of WC2, 4-5-1, goaldiff -23)*
Preds (62 points, 27 back of WC2, 2-8-0, goaldiff -59)*
* Away games
The Jets are the only team they face with a positive goal differential. Combined last-10 record of 31-31-8 (.500) and combined goal differential of -106. If you exclude the Jets, it's 24-28-8 (.467) and -190. That's an easy 5-2. Probably 6-1. Wouldn't shock me if they went 7-0.
The Jets last 6 games:
Utah (80 points, 9 back of WC2, 5-4-1, goaldiff -19)*
Blues (91 points, in WC1, 11-0-0, goaldiff +19)
Stars (104 points, 2nd in division, 8-0-2, +69)*
Hawks (52 points, 37 back of WC2, 1-8-1, -69)*
Oilers (93 points, 3rd in division, 7-2-1, +23)^
Ducks (74 points, 15 back of WC2, 5-4-1, -31)
* Away games
^ 2nd game of B2B
Three playoff teams, a combined last-10 record of 36-18-6 (.650) and goaldiff of -8. The Oilers game is the 2nd of a b2b. 3-3? 4-2? 3-2-1? Those seem most likely.
