Stop with this horrendous logic. If you watched Scales play and you think he's no good, make that argument. If you haven't watched him play, stop trying to tell someone who has that they're wrong. Why wasn't Scales drafted? Because he's 6'0" 230 pounds with short arms and a 4.7 40.
What did Tegray Scales do as a starter the past two years in the Big 10? I'm happy to tell you:
2016: 125 tackles, 24 TFLs, 7 sacks, 1 Int and 1 FF
2017: 89 tackles, 12.5 TFLs, 6 sacks, 2 Ints, and 0 FFs
Pretty damn good production in one of the best conferences in college football. Tegray Scales likely isn't a future superstar in the making, but he can play. He has the talent to stick on the roster and even start down the line.
Go ahead and take a look at Wade's starting LBs his final year in Denver. They were Brandon Marshall and Todd Davis. Marshall was a 5th round pick of the Jaguars. The Jaguars cut Marshall multiple times during his rookie season to put him on the Practice Squad, and they finally cut him before the start of the regular season going into his second year. Todd Davis was an undrafted free agent.
That means that Wade's two ILBs were a guy who couldn't make the Jaguars (back when they were crappy) and a former UDFA. Yet, both guys performed admirably. Wade gets quality play out of overlooked players because he knows how to identify exactly the skill-set that is maximized in his defense. Tegray Scales has that sort of skill-set, and he's a guy who should thrive on special teams.
