Not to knock on the armchair QB's analytical skills, but here's the scouting report of Aldon, written up by a very seasoned professional who's been doing this for a long time; and make a living for his write-ups.
And here's a comment specifically on his combine performance:
There's several flaws to Aldon Smith as a football player, but I've never came across a legit Draft Analyst saying being stiff/slow being one of them. In fact, he's top 10 in several credible analysts overall prospect rankings, mainly due to his athleticism.
Btw, I'm not just directing this at you brah, there's several people in this thread saying the same thing; makes me wonder if they have been keeping up with the current prospects or even the draft process. Not like I have been; heck, I've probably seen like a total of 30 minutes total of the entire 2010-11 college football, and none of which included Aldon Smith. Which is why I rely on these credulous analysts, who spend years following these kids up to this point.
