Quarles took over as Wake's starting strong safety in 2009, and has been delivering bit hits ever since. Stats were 62 tackles, 1 interception, and 1 pass defensed in 2009, 71/1/0 in 2010, and 101/0/3 in 2011.
One truth from those stats is that Quarles got his hand on a thrown football only 6 times in 3 years, or about once every 6 games. Quarles mainly either lined up in the box or moved there as the play developed, and also participated in punt and kickoff coverage units.
Quarles has extremely long arms attached to his slightly high hipped frame, and those arms help him shed blocks and grab and tackle those with the football. An extremely impressive tackler, Quarles is a bit stiff in the hips and doesn't turn exceptionally well.
As an NFL Draft prospect, Quarles is clearly a traditional Strong Safety prospect, very good in run support, big hitter, large frame with long arms and straight line speed.
He does not appear natural in pass defense and does not play the ball well. The only evidence of injury history is a concussion in 2009 that did not force Quarles to miss any games. Quarles is clearly a hard working prospect who gets a very high intangibles grade.
Strengths: Outstanding in the box, sound and solid tackler, relentless and thorough, sideline to sideline. Uses long arms to shed blockers and grab ball carriers. Has a long frame and covers a lot of ground in zone.
Weaknesses: Has the traditional track star issue - built for straight line speed, doesn't turn well, high hipped. Does not appear to have good ball skills. Can be juked in open field.
NFL Comparison: Chris Hope - Tennessee Titans."
He lacks much range in pursuit, breaks down high, struggles to take proper angles toward the football and is more of a drag down guy only. Uses his length well to wrap, but ends up running past the play too often and doesn't get many early jumps on the ball. Is slower to read and react.
He gets upright and leggy in his drop, lacking the ability to quickly transition out of his drop and turn and run. Isn't a guy you can trust in the deep half and doesn't maintain proper balance in and out of his breaks.
He's slow/stiff when asked to re-direct, doesn't anticipate throws or feel route around him and can routinely be out-physicaled in coverage because of his inability to maintain his footwork and balance.
Impression: He isn't a legit NFL safety prospect as he doesn't have the skill set to make plays vs. either the run or pass game at the next level."
Has good straight-line speed with a projected sub-4.5 40-time; also a good leaper with a 37-inch vertical, but isn’t instinctive at all in coverage."
