I can see how what I'm saying makes little sense from that summary. I'm thinking of the multiple picks high in the first round under Sashi Brown, before 2018, where they passed over QB again and again, often trading down. Weeden and Manziel were late firsts, and players not actually rated that highly, and it was only when they spent their early first on a QB (Mayfield) that the franchise changed tack on the position. The most egregious example was in 2017 when they held the pick to select Deshaun Watson and traded it away.
In the end they had to throw that ridiculous trade and contract at Watson to try to fill the game's most critical position.
However, I can see the point that selecting the likes of Manziel and Weeden are also reminders of the folly of thinking you just have to draft someone at the position. They looked bad for trading the rights to select Wentz away, but after a strong start he turned out to be a poor QB.
