No you're exactly right my friend.
Murray is a player who's career track could have gone either way (success or failure).
If he had been drafted by even a competent franchise (say, MIN e.g.), things might have been, probably would have been, different for him.
Versus as a McBride or Fitzgerald, he was a player who's success was/is influenced by the organizational infrastructure around him. He needed some help to reach his full potential.
And, of course, he received just the opposite from the fighting Arizona Football Cardinals, who never failed to put him in a position to fail.
And so his fate was sealed once Goodell called his name that fateful day in April of 2019. K1 was doomed the moment the ink was printed on the card from which Roger read.
