The veteran notched his 1,354th career point in the second period of Monday's game against the New Jersey Devils. Thornton assisted on a Logan Couture power-play goal that gave the team a comfortable 3-0 lead in a contest it went on to win 4-0.
While Thornton started his career with the Boston Bruins, he's been a staple of the Sharks lineup since being traded to San Jose for Brad Stuart, Marco Sturm and Wayne Primeau in 2005, per Hockey-Reference.com.
He was instrumental in the team's trek to the Stanley Cup Final last season, tallying 82 points—63 assists and 19 goals—over 82 regular-season games. Unfortunately, San Jose fell short in a Game 6 loss to the Pittsburgh Penguins.
Among active players, Thornton sits behind just Jaromir Jagr (1,877) in points and assists (1,126). He currently owns 975 assists, good for 13th on the all-time list.
Thornton will receive an opportunity to pass Shanahan in Wednesday's matchup against the Chicago Blackhawks. When he eventually tallies his next point, Boston Bruins great John Bucyk (1,369) and Dallas Stars legend Mike Modano (1,374) are the next two in the pecking order for him to chase down.
The current Sharks season hasn't started as smoothly as the 2015-16 campaign. The club still sits second in the Pacific Division behind the Edmonton Oilers but lost three straight games prior to Monday's win over the Devils.
If the team wants to make a run at the Cup again, the Sharks will need to find the consistency they possessed last season. As an alternate captain and veteran leader, Thornton should have a hand in any success as long as he continues playing.
