It was also the worst 5 game series a goalie ever played in the playoffs, Markstrom was complete garbage, a GM shouldn't look at those points as a wonderful performance when deciding an offer
The Flames D allowed like twenty breakaways or 2 on 1s, they should hold a lot of blame, but the truth is they just could not handle McDavid, Draisaitl, Hyman, and Kane in that series after period 1 of game 1.
I remember there was one sequence where McDavid/Draisaitl scored on basically a 2 on 1 down low, the goal was disallowed, and then the Flames allowed another 2 on 1 break down like twenty seconds later to the same two players which counted.
