Here's what Ourlads had to say about Watkins...
Two-year starter. Tall and rangy free safety that plucks the ball at the high point. One of the top athletic workouts at the Combine for a safety. A grab and drag down tackler. Not a killer, but makes the play. Drops his head when tackling at times. Always around the ball. Quick to read and react. Smooth athlete in his pedal and transitions. Long arms and big hands to control receivers. Good range and leaping ability. Can use more upper and lower strength. Instinctive player that has good anticipation and drives on the ball in front of him. Flashes a recovery burst. Better in zone than man-to-man coverage. Can match up on some big receivers in the slot. Not a big hitter but makes the play. Plays on punt return. Second/third round.
Hos, I just don't think this guy is as slow in reacting as what many have suggested.
I think he was knocked down draft wise because he's a soft tackler #1 and #2 because he doesn't "fit" the norm of what a free safety is suppose to look like. Free safeties aren't 6'5". And I think that scared off many teams. Call it the NFL draft version of prejudice.
