Imagine two violinists that both sound sound similar when playing a cheap violin, because the violin limits the performance.
Then both are given a Stradivarius to play, and one sounds like perfection and the other does not. The violin is no longer limiting the more talented violinist. But it does not increase the talent of the other violinest.
Reid is the virtuso who is able to play Mahomes the Stradivarius.
This is why you can't measure the full talent of the virtuoso, when not given the proper instrument.
PS. rumor is that Mahomes is not the only Stradivarius in the NFL.
