Position battles
The Panthers are deep at forward and their top six seems set. The most likely battles will come among the bottom six forwards, where Thornton could center the third or fourth line, Noel Acciari could play wing or center, and Mason Marchment and Maxim Mamin likely will compete for a fourth-line spot at left wing. Spencer Knight could challenge Sergei Bobrovsky for the No. 1 goalie job.
Most intriguing addition
Thornton, who turned 42 on July 2, is entering his 24th NHL season. He scored 20 points (five goals, 15 assists) in 44 games with the Maple Leafs last season and brings leadership to the Panthers but it is unsure where he fits into the lineup. Thornton said he'll play whatever role is asked of him as he seeks to win the Stanley Cup for the first time.
Biggest potential surprise
Knight made his NHL debut late last season and was 4-0-0 with a 2.32 goals-against average and .919 save percentage in four regular-season games (three starts) and 1-1 with a 2.06 GAA and .933 save percentage in two Stanley Cup Playoff games. The 20-year-old, who was the No. 13 pick in the 2019 NHL Draft, appears ready for more playing time, although coach Joel Quenneville recently said Bobrovsky will be the starter entering the season. Much will depend on the performance of Bobrovsky, who was 19-8-2 with a 2.91 GAA and .906 save percentage in 31 regular-season games (30 starts) and 1-2 with a 5.33 GAA and .841 save percentage in three playoff games (two starts) last season.
Ready to break through
Anton Lundell scored 25 points (16 goals, nine assists) in 26 games for Helsinki in Liiga, the top professional hockey league in Finland, last season. The forward, who will turn 20 on Oct. 3, scored 10 points (six goals, four assists) in seven games to help Finland finish third at the 2021 IIHF World Junior Championship. The No. 12 pick in the 2020 NHL Draft, Lundell has a good two-way game and should compete for a spot out of camp.
Fantasy sleeper
MacKenzie Weegar (average draft position: 111.4) led NHL defensemen in even-strength points (31) last season despite losing his elite teammate Ekblad to a season-ending injury. Weegar played an expanded role in Ekblad's absence, scoring 17 points (four goals, 13 assists) in 19 games after the injury with impressive category coverage (plus-17 rating, 41 shots on goal, 39 hits) in 21:57 of ice time per game. He can maintain or even expand his fantasy success with his defense pair Ekblad expected to be ready for training camp, the rise of Knight, and the addition of Reinhart. -- Rob Reese
