I put Byfield at 82 points this season if he is given regular PP1 time. If I were the Kings, though, I'd put Kempe back on his line again as the two had great chemistry together and doing so would signify a changing of the guard when it comes to L1 duties.
by the end of the 23/24 season, Byfield was rated as one of the top two-way forwards in the league. He took that a step forward in 24/25 by moving to the center position full time and continuing to build his 200ft game. As stands, he is considered one of the top defensive centers in the league and now can focus on further honing his offensive skills.
To compare Byfield to Kopitar isn't a stretch, but to compare his career to Kopi's likely will be as Kopi has been able to do it consistently, season over season, more than 90+% of players to have graced the league. Would be awesome if Byfield falls into that category, when all is said and done, but Kopi really is a unicorn.
