By the numbers: One-goal games a struggle

The Chicago Blackhawks are riding their worst losing streak of the season, dropping their last four games. They’ve been in every game and have often outshot their opponents, but they’re not getting the results.

Here’s a look at some numbers to help explain the Blackhawks’ recent play:

.400: The Blackhawks' winning percentage in one-goal games this season, which is 25th in the league. They are 12-5-13 in one-goal games. That’s a stark contrast from last season when they were among the league’s best in that area. The Blackhawks were 19-3-5 and had a .704 winning percentage in one-goal games last season.

11: The number of games out of 13 that have essentially been one-goal games for the Blackhawks this month. Nine were ultimately decided by one goal and two more became two-goal games because of empty-netters. The Blackhawks won two of those 11 games, lost three in regulation and lost six in either overtime or a shootout.

9: The number of goals Marian Hossa has scored in the month, which ranks third in the league for January. It’s the most goals he's had in a month since he also scored nine in December of 2009. He had 10 goals in January of 2009.

72: The Blackhawks' combined shot differential (shots on goal, missed shots, blocked shots) over their opponents in the last three games. The Blackhawks outshot the Calgary Flames, Winnipeg Jets and Minnesota Wild in total 198-126, including 102-69 in shots on goal, but weren’t able to pull out of any of those games.

16: The number of consecutive power plays the Blackhawks have killed off. They haven’t allowed a power-play goal in their last six games. Their penalty-kill percentage is up to 78.8 for the season.

4: The number of power-play goals the Blackhawks have scored in 34 chances in January. The Blackhawks are still fifth in the league with a 21.8 power-play percentage.

0: The number of games the Blackhawks have won in overtime this season. The Blackhawks are 0-6 in overtime games. Again, that’s a noticeable change from last season. The Blackhawks were 5-0 in regular-season overtime games and 5-2 in the playoffs. The Blackhawks and Florida Panthers are the only teams not to have scored in overtime this season.

.864: Goaltender Antti Raanta's save percentage in January. Raanta’s numbers have dropped since he relinquished the starting role to Corey Crawford at the beginning of the month. Raanta has allowed 11 goals on 81 shots in four games this month. He hasn’t had a save percentage higher than .900 in the four games. He endured the worst outing of his NHL career on Wednesday, allowing four goals on 15 shots and being pulled in the second period. Raanta stopped 246 of 270 shots for a .911 save percentage last month while replacing Crawford.

.918: Crawford’s save percentage in 10 games in January. Crawford’s numbers have picked up since he returned from an injury. He had a .907 save percentage in his first 27 games this season. His overall save percentage is now .911. He had a .926 save percentage last season.

4: The number of Blackhawks with a negative rating this season. Only Brad Mills (-1 in three games), Michal Handzus (-2 in 37 games), Michal Rozsival (-2 in 29 games) and Bryan Bickell (-8 in 40 games) have negative ratings. The Blackhawks have nine players with a plus-10 rating or better.
