Maybe a bit bigger than Clemons for the LEO (but keep in mind Raheem Brock was a LEO at around 275lbs as well) but he could probably lose a few pounds anyway to see if he can be a bit lighter on his feet. Looks pretty solid, watched him against Wisconsin and he's able to get good pressure, defends the run well and isn't reliant on pure speed or power can mix up his moves. Seems to be projected around the late 2nd into the 3rd round but I'd be happy to pick him up in the second. Much more of an every down DE with good length/range.
And yeah, Vernon Gholston is his cousin.
