The curious case of the National Championship OSU Buckeyes

OSU just won a Natty and will have anywhere from 13-16 players drafted. Possibly tying or breaking Georgia's record. However their higher round picks seem very volatile

Simmons is a first round lock and Egbuka likely as well.

But I have seen various mocks with OSU having 3-6 first rounders and its different players every time. I've seen donavan Jackson as high as top 20 and as low as 3rd round.

Jack Sawyer is usually top 40 but I've seen some mocks not even the first two rounds.

And there are about half a dozen guys that are like that. Anywhere from top 25 to barely Day 2. Why is that?
