In addition, the Seattle Kraken will take on the in a battle of the two most recent expansion franchises.With the offseason officially in the rearview mirror, there's so much to watch for as the regular season begins. Here's a look at the most intriguing storylines entering the 2021-22 NHL slate.More than 95 percent of the league is vaccinatedAs the season begins, one of the biggest talking points will be the COVID-19 pandemic. While it isn't mandatory that players get vaccinated, there's a throughout the season. These are the basic COVID-19 protocols that unvaccinated players must adhere to this season:Players who aren't vaccinated will only be able to go to their team hotel, practice facility and arena while being unable to use areas such as bars, restaurants, gyms, and pools while on the roadUnvaccinated players will also be forbidden from having teammates or visitors in their hotel roomsTeams will be permitted to suspend unvaccinated players who are "unable to participate in club activities," whether due to a positive test for COVID-19 or due to an inability to travel because of government restrictionsUnvaccinated players lose one day's pay for each day they mi s, though the league will make exceptions for players who don't take a vaccine due to religious or medical reasonsThe NHL has estimated that 98 percent of the league is vaccinated. Teams have encouraged their players to get vaccinated and there are certainly stricter guidelines to follow for those that chose not to get the vaccine.Lightning look to win third consecutive Stanley CupThe Tampa Bay Lightning have found themselves on top of the NHL world over the past two seasons with back-to-back Stanley Cups. For anyone that questioned the validity of winning the Stanley Cup in the bubble two years ago, the Lightning silenced those doubters for an impre sive run in 2021, which ended with a 4-1 series victory over the in the Stanley Cup Final. Now the Lightning will attempt to hoist the Stanley Cup for the third consecutive season. The team returns with the majority of the same roster and managed to add former defenseman as well as veteran goaltender . This time around, the Lightning will have a healthy , who registered an NHL-best 32 points in the postseason after mi sing the entire 2020-21 regular season with a hip injury.Tampa Bay will be looking to achieve a three-peat for just the sixth time in NHL history. Adam Frazier Jersey The (1947-49, 1962-64), Montreal Canadiens (1956-60, 1976-79), and (1980-83) are the only NHL franchises to win at least three Stanley Cups.Will get moved?The Jack Eichel saga has been one that has been filled with many twists and turns. Since being selected with the No. 2 pick in the 2015 NHL Draft, Eichel has become the face of the . However, that relationship has become extremely strained over the past year. In April 2021, it was announced that Eichel would mi s the remainder of the season due to a herniated disc in his neck. In May, Eichel expre sed his displeasure with the franchise over how to treat the injury. After declining to have surgery for the injury, the Sabres stripped Eichel of his captaincy last month and was placed Jose Osuna Jersey on injured reserve. It seems like a foregone conclusion that the Sabres will be forced to move Eichel. At this point, it's likely a matter of when and where Eichel ends up being dealt. Buffalo is need of a huge rebuild after mi sing the postseason for the past nine seasons. Eichel was supposed to be the centerpiece of the rebuild after signing an eight-year, $80 million contract extension prior to the 2017-18 season. Considering the injury concerns, the return for Eichel likely won't be what it could've once been.Inaugural season for the KrakenThe Seattle Kraken will become the 32nd when the 2021-22 season begins. The Kraken are going to be constantly compared to the Vegas Golden Knights, who won 51 games and advanced all the way to the Stanley Cup Finals in their inaugural season back in 2017. It's going to be tough for Seattle replicate that kind of succe s, but the franchise does have a good amount of strong building blocks on its roster. Much like the Golden Knights did with , the Kraken do have an All-Star-caliber goaltender in . It also doesn't hurt that the team has a nice mix of veterans featuring the likes of , , and , so a playoff appearance may not be out of the question.Penguins will be without , when season beginsThe Pittsburgh Penguins are going to be extremely shorthanded when the season begins. Star center Sidney Crosby is going to mi s at least the first two weeks of the season after undergoing wrist surgery. In addition, fellow center Evgeni Malkin is going to mi s the first two months of the campaign as he continues to recover from offseason knee surgery. This is a group that hasn't won a playoff series since the 2017-18 season. Over the past two seasons, Malkin has mi sed a total of 88 Trevor Williams Jersey games due to injury. Malkin is coming off of a season in which he had career lows in points, goals, and a sists. Meanwhile, Crosby has undergone two wrist surgeries in the past 13 months. In the absence of Crosby and Malkin, the Penguins will be forced to depend on veterans like , , and to hold down the fort early in the season.Will get dealt?Over the summer, star Vladimir Tarasenko requested a trade, which led many to believe that he would be moved. However, the NHL preseason is underway and Tarasenko remains on the roster. Joe Musgrove Jersey Now the Blues didn't protect Tarasenko in the expansion draft, but he went unselected by the Kraken.Tarasenko is coming off a season in which he mi sed five months due to a shoulder injury, but did return for the postseason. It appears that Tarasenko is in phenomenal shape and is being a good soldier throughout training camp. Perhaps if the Blues get off to a strong start to the season, Tarasenko will rethink his trade demands and will stay put. Right now, it looks like the team is holding onto its star winger. Will the Golden Knights break through?The Golden Knights got their franchise off to a tremendous start during their 2017-18 inaugural season when they reached the Stanley Cup Finals. Since then, Vegas hasn't been able to reach that same plateau. It looked as though the Golden Knights were going to advance to the Stanley Cup Finals last season before the Montreal Canadiens were able to eliminate them in six games. It definitely was a surprising result after the Golden Knights defeated the in the Second Round, which was arguably their most fierce competition. Now Vegas will look to finally be the cla s of the Western Confere
