Trey Lance is the biggest question mark among the top quarterbacks available in the 2021 NFL Draft. The North Dakota State product has every tool you could possibly want in a signal-caller, but only started 17 collegiate games and shut things down to focus on the draft after one appearance in 2020. That's why he's being scrutinized so closely and why he had a second Pro Day on Monday where he showed off his ridiculous arm. 

Videos from Lance's throwing session are wildly-impressive as he repeatedly launched deep strikes down field. Enjoy this group of videos, including the first one where the ball traveled 60 yards in the air with ease.

Lance is just a hair under 6-foot-4 and 224 pounds and can reportedly run the 40-yard dash in about 4.5 seconds.
