I actually think Decker and Jones would hold up fine against Gholston and Smith. Decker only struggled against Khalil Mack (due to the pure blend of speed, athleticism and strength), Mack is a better player than Smith or Gholston were.
QB: Meyer- Haskins literally just set every single season record we have for passing. He is the best pure QB we have ever had. Troy was amazing in his time and one of my favorite players, but Haskins carried the WORST D we've ever had to 12-1 and a rose bowl win, and threw 70 times for 450 yards and 4 tds in the lone loss.
RB: Meyer- If Clarrett plays 3 years, then JT, but 1 year of Clarrett or 2 years of Beanie doesn't compare to what Zeke did to win a Natty.
WR: JT (for now)- I think right now this would go to JT, Ginn and Holmes were flat out ridiculous, and I am only taking what they did in college into my considerations (which hurts Thomas for sure), but it was very close.
OL: Meyer- Very close one. The interior goes to JT, though Meyer's is only multiple Rimington winners. But I think the Tackles for Meyer were far better than JT.
DL: Meyer- The Bosas were the best DL we've had in school history. I have never seen players get as many sacks against double and triple teams as these 2. Nick doesn't get enough credit (sadly because of the lost season), but I think those 2 absolutely work JT's tackles all game long.
LB: Push- so many good LBs haha
DB: Meyer- Very close, but in the era of passing and offenses getting the benefits, Ward, Lattimore, Hooker, Conley and Roby may literally have been the best CBs in school history. Gamble, Doss, Jenkins were great players, but the game was way more run oriented back then, and PI's were frankly different. I would argue that the 2017 team had the top to bottom best D we've ever had and it was wasted because of the terrible offensive play calling (watched the Clemson game a few weeks ago, they held the game for so long while being on the field basically the entire game, such a waste)
