Great players like David Pastrňák have to elevate their games in the playoffs. Pasta always commits bad giveaways and never blocks shots, he does not look any different to Jones. All series he has been bad because he does not score any goals! That is what he does really well. 
Arcand: Maybe he has an injury!
Jones: He looks physically fine. Does not look hurt to me. 
Mego: Auston Matthews is dealing with something that you have not seen since the 1600s.
