Ask a hundred fans for a Top Ten List and you'll get at least one hundred versions, no two alike. Personally, I think Doc did a pretty good job with his, and he avoided what I consider to be the #1 fallacy with so many rankings: they rank only the players they've seen, in-person or on network television.
This list takes into account players from several eras...looks like Doc gave it some serious thought. Kudos, amigo.
I tried to avoid recency bias. It is very tempting to consider Jeremy Kerley, Turpin, Boykin, Verrett etc because they were amazing players that created a lot of excitement during moments of their career. In the end, I was thinking about how they matched up against others of their era. Lilly was a clear first round draft pick. Ki Aldrich was the first player chosen in the draft his year. Baugh and O'Brien are clear standouts. Swink was robbed of the Heisman he deserved because they rarely gave it to underclassmen and there was a definite East Coast bias at the time. But he was the best of the best during his junior season. Tomlinson was the Doak Walker winner and Heisman finalist and held the single game rushing record for many years. So, for me, only 4 positions are really in play for the rest of the pack. There are many older offensive and defensive linemen who deserve recognition, but I cannot distinguish between them, so I went more with position players with the exception of Jerry Hughes, who was All-American and very highly regarded. Kenneth Davis, like Boykin, has a bit of a stain on his TCU accomplishments and had an unceremonious end to his TCU career, but he was outstanding and I could not leave him off my list. Josh Doctson was the only one I allowed my recency bias to creep in. His abilities, in my mind, are what made Boykin a star. Therefore, I gave him the nod on my list. Renfro is the one no one ever seems to mention but, I think, deserves to be there.
