I think Luckett is the obvious answer.
Trent is an interesting case because of various factors that kept others from offering him. It would be interesting to see how he would have rated if there were recruiting rankings like there were today.
Since recruiting rankings started to become a bigger thing, I think Troutman probably was the highest rated player. As someone mentioned, he was ranked as one of the top 75 in the country. I don't think Ohio's had another top-100 guy since. I think most of the top-rated players at Ohio were just outside of that range. Some of the best players Ohio has had like Hunter and Cooper probably weren't even that close to being top 100, though they proved they should have been.
I never knew Sonny was that highly rated. He could do a lot of things and could play 3 positions, so I guess that probably played a part in it. Probably the most versatile player (stat wise) not named DJ Cooper. Had over 1,000 pts, 400 rebs, 300 assts, and 200 stls.
He was always one of my favorite players to watch. I also got the chance to play some pick up games with him at Ping a couple times.
Who else was recruiting him? All I can find through some random Google searching is Indiana and Xavier.
