Brooks doesn't need extra credit, just regular credit. Each has 1 NCAA title. Brooks has 2 conference titles and Griffith has 1 conference title.
As far as whose weight was tougher at NCAAs, when I look at the wins each had, they look pretty similar. Each one beat 1 guy that had previously AA'd on his way to the title. Maybe this is unfair, but it's hard for me to dismiss the fact that the two top seeds on Griffith's side of the bracket (Marinelli and Lewis) were unable to finish the tournament due to injury. For me, that really diminishes the "Griffith won a harder bracket" argument.
I am not trying to say Shane Griffith is anything less than a great wrestler. I'm just saying I'm not going to rank him ahead of Brooks, a guy who still hasn't lost a postseason match.
