The Sharks have had a hard time keeping the puck out of their own net lately.
San Jose has lost three straight games, and allowed at least four goals in each of the last four. During that span, starting goaltender Martin Jones and backup Aaron Dell have combined for an .847 save percentage in all situations, and an .865 at full strength (per Natural Stat Trick).
That represents a continuation of the team's season-long goaltending woes. The Sharks entered Wednesday 31st in save percentage (.891), and dead-last in 5-on-5 save percentage (.900).
As NBC Sports' Adam Gretz observed on Tuesday, that perfomance is not befitting of a Stanley Cup contender. It also puts San Jose in some not-so-elite company historically.
Gretz found that only 16 teams have made the playoffs with bottom-five goaltending over the last quarter-century. Only two (2008-09 Detroit Red Wings, 2005-06 Edmonton Oilers) made it to the Stanley Cup Final, and every other team failed to advance past the second round.
This context should concern the Sharks, especially in light of Dell's and Jones' solid play in net prior to the last week.
From the end of the Sharks' bye week until March 11, Jones (.919 5-on-5 save percentage) and Dell (.929) were far better than before the NHL All-Star break. Jones got the bulk of the work in the crease, and his 5-on-5 save percentage matched that of his first three seasons in teal.
But since the Sharks' 5-4 road win over the Winnipeg Jets on March 12, Jones (.837) and Dell (.900) have struggled. Neither received much help defensively in San Jose's loss to the Vegas Golden Knights on Monday, but the Sharks haven't been that much worse in their own end in front of the two goalies -- at least at full strength.
In the last four games, the Sharks have allowed 5-on-5 scoring chances (22.14 SCA/60) and dangerous chances (7.7 HDCA/60) at lower rates than they have on the season, according to Natural Stat Trick. Per their data, Jones has actually faced 5-on-5 shots at a further distance (42.88 feet) in the last four games than the season as a whole (36.11 feet).
It's possible that Jones and Dell are just experiencing an ill-timed blip on their season-long radar, which is a definite possibility considering how small of a sample size we're dealing with. That's also why their penalty-kill save percentages over that span, in fewer than 11 minutes of shorthanded action apiece, aren't all that meaningful in terms of predictive power.
You could probably say the same about each goaltender's improvement after the All-Star break, too. The full-season sample is far more meaningful as the postseason nears, and as Gretz noted, it's far from encouraging.
Jones has turned it on each of the last three postseasons for San Jose. He posted a higher save percentage in the playoffs than the regular season every time, including during the Sharks' run to the Stanley Cup Final in 2016.
If San Jose is going to get back there this spring, he'll have to heat up in a hurry.
