It all comes down to a GM who can find the guy; every year the media has two "darlings" that they think are the two best QB prospects; so they have something to write about during the slow season of the NFL (SB to Draft, time frame)
Go through this list and eyeball good QBs on it must are drafted middle to late first round or even later rounds very few of the media darlings hit in the long run

On a side note i also thing a lot of the top prospects go to dysfunctional franchises and just die there; imagine if Bryce Young was drafted by SF
