Going along with the goaltending, you need good defense. Even though it's impressive to see goalies post those high-number saves, you don't want them under constant attack. The law of averages will eventually take over, and pucks will get past them, no matter how good they are. In Game 7 of Dallas/Calgary, the Flames outshot the Stars 67-28. Now, that game did end up going to OT, and the Flames won, because poor
Jake Oettinger could only do so much. Game 1 of Colorado/St. Louis also went into OT, and the Avs came out on top with 54 shot to the Blues' 25. If the other team is getting that many opportunities to fire on your goalie, you've got some holes to fill.
Clearly, the Hawks need some strength and depth in their defensive lines to help their goalies, and actually give them a chance.
In the 32 games that
Kevin Lankinen played, he faced 973 shots, which averages to about 30.4 SOG per game. That's too many.
Collin Delia only played 8 games, and he saw 218 shots come his way. Fleury saw the most with an average of just over 31 SOG per game. In his 6 months with Chicago, he played 45 games, and faced 1,398 official shots on goal - keeping in mind that pucks hitting the posts do not count. But we all know who to thank when those don't go in.
