Belongs in draft forum but I wish I knew more about this guy A free safety who stands almost 6'4'' and weighs 224 lbs,runs a 4.4 forty,has a 6.88 3 cone drill,has 34 5/8 in long arms...freakish numbers...CAN HE PLAY????? Free safety Quentin Scott impressed scouts from eight teams at Northern Iowa’s pro day on March 31st. Scott (6-3 7/8, 224) worked out as both a defensive back and a wide receiver and put together a really good workout. He ran a 4.40-second and 4.45-second 40-yard dash, had a 35-inch vertical leap, 10-1 broad jump, 4.18-second short shuttle, 6.88-second three-cone drill and completed 13 bench press repetitions at 225 pounds. His arms were measured at 34 5/8 inches
The physical attributes can only take you so far. There is far more to the effectiveness of a player on the field beyond just their height, weight, and drill times.
