I'd trade you a second. If you're looking for more data points, his DLF value is around a 220. A next-year first rounder goes for about 253, so you're looking at early to mid-second value. He should pull more than jabarony's third, though that's jabarony's personal preference. Just, if you shop around, you might get something equivalent to that. To put it in perspective, Henry Ruggs is going for around 120 or so, right there with Denzel Mims. Aiyuk is at 400, Higgins around 370, etc., etc.
Shenault carries some cachet with him. KeepTradeCut has him at about the 2.01 spot.
YMMV. Calcs are just that -- they're calcs.
I'd give you a late second for him, probably no more, but I'm scared of Urban Meyer's plans for him while others seem to go gently into that good night. I say rage, rage against the dying of the light.
