There were more than 1,700 student-athletes at Saturday's Dallas Nike Football SPARQ Combine, so keeping up with all of the quality athletes was a difficult task.
Nevertheless, Scout.com saw plenty of great ones, including some underclassmen. Here's a closer look at a few of those younger prospects (SPARQ scores are unofficial until next week, according to Nike.)
Obi Eboh, 2016 CB, Southlake (Texas) Carroll -- one of several tall, long defensive backs in the younger grades, the 6-foot-1, 172-pound Eboh had a strong testing performance with a SPARQ rating north of 95 that included an impressive 4.57-second 40-yard dash.
Chris Miller, 2016 FS/CB, Frisco (Texas) Lone Star -- Miller has good size (6-0, 174) and posted a 4.58-second 40, which helped him to a strong 100+ SPARQ rating. He plays free safety for Lone Star, but could possibly convert to a cover man.
Spencer Misko, 2017 DE, Keller (Texas) -- the first thing that stood out about Misko was his size at 6-foot-5 and around 210 pounds. Don't sleep on Misko's 75+ SPARQ score; that's solid for a tall, long defensive end prospect still in his freshman year of high school. The 5.07-second 40 was a good effort from Misko, who said he plays an odd-front end in Keller's 3-4 scheme.
Cameron Murray, 2016 DT, Bryant (Ark.) -- Murray was as impressive as just about any underclassman. His 86.19 SPARQ score was only three points shy of The Opening invitee and five-star 2015 defensive tackle Daylon Mack. At 6-foot-2, 272 pounds, Murray ran an strong 5.04 40. Murray appears to be a scheme-versatile interior defender capable of playing 3-technique or nose.
Jeffrey Okudah, 2017 ATH, South Grand Prairie (Texas) -- Okudah is generally classified as an athlete right now, but given that he's already 6-foot-1, 190 pounds, he's physically suitable for multiple spots. He had a great SPARQ score of 94.23, which is very high for a 2017 prospect. Safety and outside linebacker could be potential fits for him.
Michael Onuoha, 2016 S/CB, Austin (Texas) Anderson -- Onuoha's size really jumped out at me. He's a 6-foot-3, 171-pounder who plays cornerback. That must be a nightmare for opposing receivers. He backed up that size with 40.9-inch vertical, which ranks in the top 20 nationally of this year's SPARQ combines. He also ran a 4.63 40 and finished with a SPARQ score of 100.17. Given his size and explosiveness -- his peak power wattage output measurement was in the 98th percentile for his class -- Onuoha may move to safety at the next level.
