This week, I checked in with progress reports for quarterbacks from the 2018 NFL draft. Five quarterbacks were drafted in the first round that year, and I took detailed looks at Lamar Jackson (Tuesday), Josh Allen (Wednesday), Baker Mayfield (Thursday) and Sam Darnold (Friday). Sorry, Josh Rosen; I'll get to you another time.
If you were crafting a quarterback prospect from scratch, you would likely end up with something close to Sam Darnold. The New York Jets quarterback has prototypical size and arm strength.
