The career high doesn't matter if Zegras only has like 20 points in his last 2 years and is pacing for like 16 points this year.
It's not like it was ages ago. One injury plagued year last year where he played hurt and out of position, then broke his ankle.
And have you checked his splits at LW vs C? He's played around the same number of games at each position the last two years, but overall he's gotten 15 of his 19 points at C. Which is probably why they've finally given up on the LW experiment the last two weeks.
But sure, Puustinen is very similar to Zegras at LW. Problem is, Zegras as a LW .... sucks.
