Couple of older reports on Lysell that do seem to back up the Divver report.
McKeen’s 2021-22 Yearbook - There are many players out there with great feet and many others with great hands, but only a handful who combine speed in all limbs as well as Lysell. He is electric in transition, constantly forcing defenders back into their heels as he gains the zone with speed, His hands are soft and creative. He can change direction faster than many of his peers can skate in a straight line. Additionally, he will look to play the middle lane, not content to stick to the outside like many players of his ability and stature would. Without question, he has as much upside as any forward taken in 2021, and that is why the Bruins chose him at 21st overall.
There are certainly some perceived concerns over his selfishness on the ice and his overall awareness and ability to consistently get the best out of his skill set, one of the reasons he fell to Boston. However, he is a long-term commitment. Lysell has signed with Boston and intends to play in North America this year. Whether that is in the AHL or in the WHL with Vancouver, remains to be seen. However, if his development goes according to plan, Lysell could develop into a high-end top line forward for the Bruins.
From McKeen's Draft Preview:
For as exciting as Lysell’s play can be, there is a chance he is not only not a top ten pick but could fall substantially further than that. This risk is mostly related to off-ice issues that will be judged differently by different teams. The details are sketchy and vary based on which unverified source is consulted, but the general consensus is that while he might lose to another player if the team in question thinks they can provide equivalent value on the ice, the issues, whatever they are, are not toxic or expected to impact his long-term development, which many agree gives him first line upside.
