John Tavares playing his first game for the Toronto Maple Leafs against the New York Islanders and the start of the 2019 IIHF World Junior Championship are among the highlights of the week ahead.
Here's a look at 5 things to watch:

1. Tavares, O'Reilly face former teams

John Tavares will play the New York Islanders for the first time with the Toronto Maple Leafs at Scotiabank Arena on Saturday (7 p.m. ET; ESPN+, CBC, SN1, MSG+, NHL.TV), the headliner of the second 15-game day this season and 15th in NHL history.
Tavares, the No. 1 pick in the 2009 NHL Draft, had 621 points (272 goals, 349 assists) in 669 games with New York and was Islanders captain from 2013-18 before signing a seven-year, $77 million contract with the Maple Leafs on July 1. The 28-year-old center has 42 points (24 goals, 18 assists) in 37 games and is a big reason why Toronto (25-10-2) is a top tier team in the Eastern Conference. His NHL career high for goals is 38, set in 2014-15.
Ryan O'Reilly will face the Buffalo Sabres for the first time with the St. Louis Blues at Enterprise Center on Thursday (8 p.m. ET; FS-MW, MSG-B, NHL.TV).
