I had never heard of Covington when we drafted him, so I went and looked him up on Mock Draftable (
https://www.mockdraftable.com/player/chris-covington), and was like "he's got NFL measurables, it's the 5th round, whatever." But so far, he looked like a good 'un. McClay and co. seem to have a knack for Big 10 LBs.
With Wilson, Thomas, and JML all with one-year contracts, I can see how the scouts might fight to keep him on the roster, especially since he might be good enough to get poached off the PS.
