Penn State wide receiver Allen Robinson, the No. 34 overall prospect in the rankings and seventh-ranked receiver, showed Tuesday much-improved burst and the kind of explosiveness some scouts expected at what proved to be a marginal workout at the Scouting Combine.

With a 4.47 time in the 40, 42-inch vertical and 6.53 three-cone at State College, Robinson vastly improved his athletic results from Indy: 4.60, 39-inch vertical, 7.00 three-cone. He also added four inches to his broad jump (131 inches Tuesday).

The effort to show more suddenness was evident in Robinson's frame. He weighed 220 in Indianapolis and was 208 at pro day.

Robinson left Penn State with one season of eligibility remaining as one of the most productive in conference history with a combined 174 receptions and 2,445 receiving yards.

Among those present from NFL teams were Eagles head coach Chip Kelly and Steelers head coach Mike Tomlin.
