Strengths and weaknesses of the NFL draft's top QBs

Top quarterbacks impress in different ways during pro days (0:59)

Whether it was a big arm, off-the-charts athleticism or performing in the rain, this year's top quarterback prospects turned heads during their pro days. (0:59)

I've believed that Sam Darnold is the best quarterback in the 2018 NFL draft throughout the process leading into April. He has been the first overall pick in all three of my mock drafts, and I think if you polled league personnel, Darnold would get the most votes. Majority doesn't matter much when it comes to the Cleveland Browns' choice at No. 1, though -- general manager John Dorsey and his personnel staff own all the votes.

But like the other top quarterbacks, Darnold also has shortcomings, which is what makes this year the most fascinating in terms of evaluating QBs since I've been at ESPN.

Here are the strengths and weaknesses of the top five QBs -- Darnold, Josh Allen, Josh Rosen, Baker Mayfield and Lamar Jackson -- as well as what I'm hearing from NFL personnel about potential landing spots.
