Sabato:
No, Sabato was not a "horrible" draft choice. Did he have a "good" season (from a fan perspective), no he did not. But you appear to be glossing over the fact that he continued to make adjustments and actually started to improve as the season went on. Again, not monumental improvements, but they were clearly there.
Just as you cannot anoint a player the next GOAT and future 1st ballot HOFer for a standout first Pro season, neither can we notify the Inquisition and burn the draftee at the stake for the heresy of (gasp!) attempting to play the sport he loves because a team drafted him. Besides, players "failing" after being drafted is the norm, not the exception.
Lewis:
We shouldn't legitimately care or even entertain the thought of where any prospect is ranked (other than as fan clickbait). Who "ranks" prospects? Sportswriters... not people who actually play/coach/evaluate the game.
Lewis, and Sabato for that matter, will be fine... until such a time as they are not.
I, like you I assume, and many others would love the instant gratification of a player just taking off and leaving little doubt in our minds and then having that hope of success justified by the talking head sportswriters singing their praises.
At the end of the day, all we are left with is faith. When it comes to baseball, you have to have it or otherwise all you ever see is... "This inability to draft difference makers, coupled with Pohlad's cheapness and Falvine's aversion to make transformative trades, dooms this franchise to mediocrity."
