You gotta keep trying until you find one. Look at Arizona drafting Rosen and then Murray a year later. Not saying Murray is great but he was a huge upgrade.
They were drafting #1
The Bills expended Seven 1st and 2nd round draft picks until they got Josh Allen. The Jets even more
Rob Johnson, Todd Collins, #1 on Drew Bledsoe, JP Losman, EJ Manuel, Tyrod Taylor, Cardale Jones: all post Jim Kelly. A span of 26 years.
You can roam in the wilderness for a very long time.
Jets: Zach Wilson, Sam Darnold, Christian Hackenberg, Geno Smith, Mark Sanchez, Kellen Clemens, Browning Nagle
Dolphins: Tua Tag, Ryan Tannehill, Pat White, Chad Henne, John Beck, this is just since 2008. 5 picks.
