Magical best based on ONE match on really seaming wickets where other bowlers also bowled great?
A rather overwrought argument, no, to say nothing of tiresome and mean spirited.
You may certainly argue that expectations regarding Amir seem disproportionate to the sum total of his achievements so far. But by what standards, and of what player can it ever be said that expectations of them were always just about spot on, neither too rosy nor too pessimistic? That they never disappointed, nor exceeded expectations?
So far in his still short career Amir has done both in spectacular fashion.
Among those who he has accordingly impressed are former players like Wasim Akram and Michael Holding.
Let us acknowledge that it is impressive when these kinds of people are impressed. When Akram says that Amir is more talented than he was, at the same age.
Let's acknowledge that being the youngest ever bowler to take a five at Lord's seems a rather impressive feat.
You may point out that others also have done well in similarly helpful conditions. But they weren't
17 at the time. Someone suggested Amir may struggle as he gets older and his pace declines.
Which may be true, and is a problem faced by all fast bowlers. But if Amir's development follows that of
other fast bowlers, he will for the next three- four years only get faster. And better.
That is one of the reasons for why expectations on him may yet outpace his performances for
some time.
