In high school Bryan was an offensive lineman....all state as a matter of fact. But,he didn't want to play that side of the ball and Florida was the only major program that was willing to play him on defense. So, basically no experience as a DL, instincts and awareness are low,and being buried on the depth chart for two yeasr before getting his chance to start (Jr. year) are reasons for his low numbers.
Don't get too caught up with the production numbers on Bryan, and be mindful of the plays were he was a disruptive force and wasn't credited. He probably has the highest ceiling of any DL in the draft...it's just going to take a year or two to harness the talent.
Here is an interesting article about Tavan's roots...
