He used to be a decent 5v5 player and is no longer, not sure why you fanboys can’t admit this
Maybe you need to articulate yourself better, from some of your posts I really got the idea you think he was never any good 5v5 and never will be any good 5v5. The former clearly isn't true and you don't need to go back that far to find out - IMO he played his best 5v5 hockey in CBJ 21/22 & 22/23, it just went largely unnoticed because the team was so bad and he didn't play full seasons. 21/22 for example he was the only guy in the team to reach 50% GF 5v5 and was 1 P/GP when the next best producer was something like 0.75 P/GP. Similar story in 22/23.
His even strength production those years was pacing for top20 in the league - while playing 1st line with largely AHL defense in a bottom-3 team and having a point on over 80% of goals scored while he was on ice. Basically if the team managed to do anything offensively, he had his hand on it. When on ice ofc, not from the bench.
Yes, he missed significant time both season and "on pace" is not same as actually doing it, but let's not act like a 55 game season is completely insignificant and tells nothing about the player.
So clearly he can be a good 5v5 player, will he be that again in the future who knows, if health permits I see why not, but will it? His injury history is extensive and that knee he hurt in preseason already had 4 prior surgeries on it including at least one that was pretty major. It's entirely possible his skating will never be the same. Even if it won't be, I'm sure he can adapt to some degree and be better than this even with a bum knee, especially if he can play with linemates who can actually carry the play a bit, he could still be a decent 2nd liner. He could also be the best or 2nd best forward of the team next year (5v5) if he heals fully and gets his game back.
IMO some patience would pay off, just enjoy the PP goals for now and see how the overall game shapes up.
