Kopitar is still a very good player but he doesn't look as good as he could look because he is playing too many minutes.
That said, he is still right on pace for his career average in points per season (72) and he's cranking on face-offs with a 57% win percentage. He's a minus player though but, IMO, that could be cleaned up if he wasn't playing so many minutes.
He's still catnip for an NHL coach. Giant center that wears the "C", easy to coach and is going to go out and put up 20 goals and ~70 points.
It's much easier for T-Mac to just tap him on the shoulder and send him out when he is trying to win now than show some restraint and think about the bigger picture. Then again, Blake was supposed to be a "got to get this guy as GM before he is snapped up" guy like some kind of wunderkind but it has all been paint-by-numbers right down to the T-Mac hire who is also paint-by-numbers.
It's like the Super Bowl. If Zac Taylor calls two plays for Chase on 3rd and 4th & 1, he doesn't get criticized as much since he was going to his stud even if the plays don't work. Instead, he called for a handoff to the back-up RB on 3rd and 1 and has rightfully been dragged for it. T-Mac is going to live and die by riding 11 & 8.
As for comparisons to Kopitar, Byfield is nowhere near as good at the same age. He's not as good as 34 year old Kopitar. Anze was playing against men in the WC his draft year while Byfield was running 3C at the WJC in his D + 1.
My biggest criticism of Byfield has been a tendency to defer or just blend in and not just go out and assert himself. I think
@bland mentioned it that Durzi is pretty much the only prospect that has come up this year that just went for it, seized his opportunity and didn't let go. While I hate Byfield's linemates, he needs to act the part regardless. If you have that much skill and natural talent, it should shine through more and it is too easy to blame coaching for a player playing timid hockey. Not a T-Mac fan but I don't think they are telling every prospect besides Durzi to play scared.
