2019 NFL Draft: Here are the top underclassman draft prospects you need to know

The deadline for underclassmen to declare for the 2019 NFL Draft came and went, and as usual, there's a plethora of top prospects from the redshirt sophomore and junior ranks who have declared.

Highlighted below, by position, are the top underclassmen draft prospects, along with a one-sentence scouting report of each, which is much more difficult than it looks but something I've found to be a useful exercise during the pre-draft process.

Quarterbacks

Dwayne Haskins, Ohio State

Kyler Murray, Oklahoma

Small, athletic marvel with tremendous pocket patience, good accuracy, and plenty of arm strength.

Daniel Jones, Duke

Tall, traditional pocket passer with tendency to make ill-advised, off-balanced throws yet works the quick-passing game well and has the athleticism to be utilized as a runner.

Tyree Jackson, Buffalo

Imposing physical specimen with nice touch downfield, big arm, and serious athleticism who's raw reading coverages and going through his progressions.

Also declaring: Jarrett Stidham, Auburn
