Kind of makes me wonder if he’s not willing to put-in the work.
These guys know they are going to the combine. He could have slimmed-down a bit to help with his drills and 40 yard dash.
Here’s part of an article I found:
Derrick Brown, DL, Auburn
To start, I need to be clear about my evaluation of Brown’s combine. I don’t expect his performance in Indianapolis to impact his draft position. He’s likely going inside the top 10 overall, and it’d be a shock if he makes it to the second half of the first round. This warning strictly pertains to the amount of long-term success I believe – and the numbers suggest – he’ll have in the NFL.
Size needs to be factored in with Brown’s workout. Among defensive linemen at the combine over the past two decades, his height (6-feet-5) and weight (324 pounds) placed in the 84th and 94th percentile, respectively.
However, all of his measured, on-field work was historically bad. His 8.22 3-cone placed in the third – yes, third – percentile among defensive tackles. His vertical? 22nd percentile at the position. His broad jump was a respectable but far from super-impressive 66th percentile. His short shuttle time of 4.79 – 18th percentile. Ndamukong Suh – a trendy comparison for the Auburn star – was light years more athletic than Brown when he tested at the combine in 2010.
And Brown’s workout basically matches the film. While young – still not 22 – Brown wins with sheer force through blocks and tremendous block-shedding laterally to go along with stellar tackling reliability. He’s the best run defender in the class, bar none. But, while that makes for fun highlights, it’s simply not as valuable in the NFL in 2020 as it was even a decade ago.
He took a step forward using his hands when attacking upfield in 2019, yet outside of a bull rush and a very rare swim, one simply can’t say Brown is a refined hand-work master on pass plays. And, now, projecting him to win through a gap simply with his burst and athletic gifts at the NFL level might be a fool’s errand.
What that leaves is a large, intimidating defensive tackle with easy-to-see strength and an advancing yet not loaded arsenal of pass-rushing moves with well below-average athleticism for the position. For as disruptive as Brown was during his illustrious career at Auburn, the odds are now firmly against him becoming a star (pass-rusher) in the NFL.
