That's fair, every player has a chance to bust, so even if they take a "safe" pick, there's no guarantee they work out. But based on watching game tape I think these QBs have almost 0 chance to become franchise QBs in the NFL. My view of it, which isn't necessarily right, is that if we take a QB this year they will never become a great QB and we're basically drafting Mitch Trubisky or Dwayne Haskins. Why would we use a 1st round pick on players we already have? Also, if we take a QB this year, I don't think we try to get one next year when the class is generally regarded to be better.
So, you're viewing it as well if both can bust, take the QB because if it hits the positional value is higher (I think that's how your viewing it at least). In my view, the QBs are busts, 100%, so why take a bust instead of a player with potential opportunity.
I could be wrong, I have definitely been wrong in the past. In 2017 I wanted us to take an ILB and when Rueben Foster was on the board still I was hoping and praying he'd be the pick, and they went Watt instead, which I didn't like. Obviously, I was incredibly wrong.
My philosophy as a fan is that there's definitely players I love in the draft and hope the Steelers take, or others they avoid, but as soon as they get drafted, I support them 100%. I didn't want us to take Najee and go "all in" for Ben's final year when I didn't think we had a Super Bowl contending team and had many other needs, but as soon as he was drafted I support him and hopes he turns into a HOF talent.
