Simpson was recruiter or co-recruiter of the DL Class of 2019 (Harvey, Cameron Williams, Blissett, Harrison-Hunte and Holley). These are his kids. Blissett is a medical. But the other four need to perform now.
That said, I think if you find a Phillips type on the market, you'd be insane not to take your shot. I don't think anyone so far shows they're a step function better than what we already have on roster.
