At the moment it is hard to develope O-line player and QB IMHO. To see so much top round Oline player play really bad in the last 3 years is troublesome. And there are much more than QB that bust out or don't amount to anything.Hard to develop them...that's the issue.
We need a good O-line coach and a good QB coach and a good prospect, I can see Mayfield Darnold and Jackson as somehow QBoF but I didn't see enough tape to be sure who will be it. Last year I didn't like Kizer or Turbisky, but who knows.
Maybe a good prospect falls to us at 10-15 hopefully we get the guy and can develop him to a good or maybe with some luck to a great QB (with a little chance to the GOAT QB, that would be nice XD, winning 6-7 SB in the next 18 years XD.)
We will see, now we need to know where we draft and who will be our coach, with Arians ... many of the prospects at QB don't make any sense.
