I think this is a bit overstated, actually. I agree with the sentiment if they make the move up the board to get a QB. If they do that they have to have the conviction that he’s the one.
If they stand pat and draft the next guy on their board at 21 or 22, while it would suck to be wrong about him and it leaves the team in the same QB purgatory, you haven’t made the sort of investment that would prevent you from addressing the position again the next season, and it won’t cripple the franchise if you had to cut bait.
