During his lockout to lockout (dead puck era) Leafs tenure, Sundin played his 23 -32 year old seasons. During that time he was 2nd in points and 1st in goals, among NHL centres, but tied for 5th with Modano in Points per game with Modano.
Offensively at C there was a pretty clear top tier of Sakic/Forsberg/Lindros/Gretzky (retired halfway through)
then a very very strong 2nd tier of
Modano/Sundin/Yzerman/Fedorov/Weight/Turgeon/Francis/Oates/Roenick.
Quick look shows that over that time Sundin's league wide point finishes were
1x top 5, 1x top 10, 3x top 20, 4x outside top 20, no major hardware.
Matthews is currently in his 1st season of that window.
Sundin was an excellent player, but his calling card was longevity and consistency.
