Hard to say... If I could choose whoever I wanted, then based on team needs hands-down I'd choose Adolphus Washington. I'm guessing that DT depth is going to be an issue next season with only Tracy Sprinkle, Michael Hill, and Donovan Munger next year at that position group. It was the main reason I was so bummed that Ohio State couldn't lockdown Rashard Lawrence, we could really use a big space-eater like him next year/the near future.
Since, I'm limited to just the early entrants, I'd probably go with Joey Bosa for pretty much the same reason. It doesn't completely solve the DT depth, but it would give the LJSr./Fickell some flexibility with DL rotations since Bosa can play inside based on match-ups... especially since Hubbard and Lewis have shown that they can hold down the DE spots without issue.
Sorry guys, not to be a Debbie downer, but I'm just extremely worried about interior DL (some for 2016, even moreso for 2017). I'm not super familiar with OSU's 2017 targets, but I'm really hoping we land a big fish (figuratively and literally) at DT.
Or... maybe I'm just worried for no reason, and a guy like Malik Barrow comes out of nowhere to ball out at DT for the next 2-3 years.
