Kenneth Darby

positives

Has a short, compact frame with good upper-body thickness, muscular arms and legs, broad shoulders, big bubble and thick thighs and legs...Creative open-field runner with that sudden burst of speed that allows him to immediately gain an advantage through the rush lanes...Elusive cutback runner with precise plant-and-drive agility. He has the body control and lower-body flexibility to stop and go with no wasted motion and is effective at utilizing head fakes and his hip wiggle to set up the opponent...Alert athlete, especially when it comes to recognizing and locating the blitz and bull rush...Needs only minimal reps to retain and takes the plays from the chalkboard to the playing field...Most featured backs shy away from blocking assignments. Darby relishes playing the role of blocker, as he is a tough, fiery type who will not hesitate to mix it up in the trenches...Explodes out of his stance through rush lanes and is very decisive attacking the holes...Has the loose hips and wiggle to make the initial tackler miss and stays low in his pads to burst through the pile...Runs with short pitter-patter steps and is very fluid redirecting...Very deceptive varying his speeds to break free along the perimeter...Has the burst to outrun defenders when working in space and most of his long runs have been the result of his explosive second gear...Shows a very good feel for rushing lanes and the vision to quickly locate cutback routes...Excels at anticipating even the slightest of creases and, based on the poor performance of the Tide's 2006 offensive line, most of his yardage was the result of his own hard work, as solid blocks rarely developed for him...Has that explosive second gear, hip snap and balance to be much more effective turning the corner than running between tackles...His hip shake and wiggle allow him change direction in an instant and run through cutback lanes...Slippery runner who is very difficult to bring down in isolated coverage...Possesses an array of moves to elude, especially when changing direction...Protects the ball well by keeping it close to his body, usually carrying it away from the defender (is ambidextrous)...Quick to uncover and has the anticipation skills to work back to the ball...Effective cut blocker with enough hand strength to lock on and sustain...Quick in the open, using angles properly to locate second-level defenders...He shows good alertness picking up the blitz and has a quick kick-slide in pass protection.

compares to

DeANGELO WILLIAMS, Carolina Panthers (Memphis)...Darby is bigger than Williams, but both rely on their exceptional burst, outstanding field vision and instincts with the ball to be slippery outside runners. Darby has a great feel for the crease and cutback lanes, but relies more on his elusiveness, as he doesn't have the ideal strength to be a power runner.

negatives

Frame could carry some additional bulk, but he is too close to maximum growth potential to add without it affecting his quickness...Was forced to create on his own, as he could not be patient waiting for blocks to develop, which resulted in 23 negative-yardage runs by Darby in 2006, uncharacteristic for this player...Will not hesitate to take the ball up the gut but, because of some size limitations he had to rely on his line to create space and they failed to do so in 2006....Type of player that needs room to run and can get bottled up inside, where his leg drive is only adequate...His 2006 early-season knee bruise contributed to Darby being tackled behind the line of scrimmage 13 times in the team's first four games; he was also stopped five times for no gain during that span...Executes excellent jump-cut moves, but just seemed a bit frustrated that he had little or no room to execute these moves in 2006...Will run the ball hard up the gut, but unless he redirects or bounces wide, he is not the type that can break many tackles taking the ball up the middle...Has good weight-room strength, but needs room to operate and seems to get too narrow with his base when having to power through arm tackles...Doesn't have the long arm reach to compete for the ball at its highest point (29 5/8-inch reach) in passing situations.

2003: Sat out the Arkansas (9/27), Southern Mississippi (10/11) and Tennessee (10/25) games with bruised ribs and sprains to both shoulders. 2004: Underwent surgery in January to repair a sports hernia after suffering a pelvic injury early in the first quarter vs. Minnesota in the Music City Bowl (12/31). 2005: Bothered in August camp (8/12) with a sports hernia that prevented him from participating in spring drills. 2006: Suffered a left knee bruise in practice (8/21).
