Buckeyes dominate Mel Kiper's first 2016 Big Board

Welcome back to another season of college football and prospect-watching. If there's a theme for the first Big Board of the 2015 college football season, it's that last year's national champs aren't going to be short on talent in the quest for a repeat. Five Buckeyes dot the initial ranking of top prospects for the 2016 NFL draft. It's a defense-heavy group at the top, and there will be some major health issues to watch, especially because many of the top players have put on some mileage after starting from Day 1.

A reminder: General scouting reports on these players won't change week to week, unless my overall evaluation changes. I'll simply be updating performance notes and providing updates on key matchups to come.

An asterisk denotes a junior for the 2015 season.

1. *Joey Bosa, DE, Ohio State Buckeyes

He'll miss the first game due to suspension, but he's No. 1 here. His dad was my No. 3-ranked defensive end in 1987 and eventually went No. 17 overall to Miami. The son won't fall that far. Bosa has size (6-foot-6, 275 pounds and could play bigger), versatility that will fit any scheme and the ability to go around blockers or right through them. He has 34.5 tackles for loss in two seasons, and remember that so many guys who produce that well early had a redshirt.

2. *Laremy Tunsil, OT, Ole Miss Rebels

The key with Tunsil is health, because that's been the one knock so far in a stellar two-year run. When healthy, he's the best pass-blocker in the draft, a guy who wouldn't look out of place if he had to play on Sundays this season. He's a nimble but powerful left tackle prospect, and has all the traits you look for at that spot. If he's healthy, he's an early pick.

3. *Jalen Ramsey, CB, Florida State Seminoles

While it doesn't dramatically shift his status as a prospect -- he'd be in good shape either way -- Ramsey will line up at cornerback this year after playing safety last season. A does-it-all talent who has already started 28 college games heading into this junior season, I would have rated him the top safety taken in the 2015 draft. He has the length, range and exceptional instincts to make plays all over the field, and I expect a smooth transition to corner. He is a truly gifted athlete.
