The 6-5, 225-pound Cumberland turned 40-yard dash times of 4.47 seconds and 4.48 seconds. His time of 7.2 seconds in the NFL L-cone drill was also dazzling.
Cumberland's 40-yard times were among the fastest recorded at the camp. They were run on the turf indoor practice field at Akron, a track not considered to be fast.
Cumberland put his speed on display in receiving drills, getting behind defensive players for at least two long touchdown receptions.
"Jeff Cumberland, what you did today was sick," said one of Scout.com's recruiting experts at the end of the day.
Cumberland was among roughly 150 prospects in attendance at Saturday's combine. The event drew prospects from 11 states and the District of Columbia. Coaches from Marshall and Akron, among others, were also on hand.
We will have a video interview with Cumberland loaded later this week. He said he was awaiting scholarship offers, naming Ohio State among his short list of favorites.
The players went through five testing stations in the morning – 40-yard dash, standing broad jump, vertical jump, pro shuttle and NFL L-cone drill. Then, in the afternoon they participated in position drills and went one-on-one against other players in passing and blocking drills.
Here were more observations from Saturday's combine:
* OSU verbal Chris Wells, a running back from Akron Garfield, had a 4.4-second pro shuttle time to go with 40-yard times of 4.50 and 4.51 seconds. Wells is 6-2, 230 pounds. Wells left before the afternoon position drills.
* OSU verbal Ross Homan, a linebacker from Coldwater, Ohio, had 40-yard times of 4.69 and 4.71 seconds. His shuttle time was 4.72 seconds. Homan, who measured 6-1, 232 pounds, had a 30-inch vertical jump. One Scout.com rep noted how Homan has improved physically since his showing at a combine in Cincinnati a year ago. At that point, Homan was clocked at 4.9 seconds in the 40.
* Macedonia (Ohio) Nordonia junior running back Jordan Mabin attended with his cousin, heavily recruited running back/linebacker Dorin Dickerson of West Allegheny, Pa. Mabin tweaked his hamstring, but still had a 4.5-second 40-yard time.
* Dickerson only participated in a couple of drills, but his 38-inch vertical leap was impressive.
* Shaker Heights wide receiver Dart Mitchell lived up to his name with a blazing 4.16-second pro shuttle time.
* Canal Fulton (Ohio) Northwest fullback/linebacker Scott Weber was clocked at 4.75 seconds in the 40.
* Huber Heights Wayne linebacker Jeff Cleveland turned a nice 4.55-second 40 time.
* Some of the most impressive performers at the combine included Washington (D.C.) Coolidge offensive tackle Lamar Milstead, Coolidge junior defensive lineman Marvin Austin, Shaker Heights OL Dominic Alford, Wooster OL Cory Palmer, Berea OL Bob Gulley, Randallstown, Md., OL Kenneth Mayfield and the Pittsburgh Gateway trio of DE Jordan Stevens, QB Aaron Smith and OL Chris Hanna.
* One prospect who had everybody's eye was Pittsburgh Gateway sophomore linebacker Shayne Hale. The 6-2, 212-pound Hale had 40-yard times of 4.79 and 4.81 seconds. One college coach in particular referred to Hale as "the next LaVar Arrington."
* We will have an update on Mabin as well as video interviews with Cumberland, Homan and Dickerson and some video highlights from the combine. Plus, Scout.com will have complete coverage as well on its home page. (Click on the red link marked Combines at the top of the page and check back periodically for updates.)
