I mean I haven't actually looked at the numbers on it but even a 40-50 point guy would probably be well above average for 20th overall kinda hard to call that a bust
if he was like 1st overall or something and only ever managed that then sure I could get behind that
looking at Mantha's draft even if you look at guys taken ahead of him here's the 11 forwards taken before Mantha,where they were drafted,and their career high in points in the NHL so far
Nathan Mackinnon,1st: 97
Aleksander Barkov,2nd: 78
Jonathan Drouin,3rd: 53
Elias Lindholm,5th: 45
Sean Monahan,6th: 64
Bo Horvat,9th: 52
Valeri Nichuskin,10th: 34
Max domi,12th: 52
Alexander Wennberg,14th: 59
Curtis Lazar,17th: 20
Kerby Rychel,19th: 9
Mantha had 48 last year which is more than 4 of those 11 guys have ever had and only a few points short of a few more of them,and these are just forwards that were taken ahead of him
then his 48 is also easily higher than anything any of the 9 forwards taken after him in the first round have ever done,and anything any of the forwards taken in the second round that year have done as well
