Some teams don't count this stat.
In the VT game alone he had 2 or 3 hurries, but they didn't count them. Same goes for like every other team stats I have found.
Texas is the only school that actually counts the hurried stat that I have seen. Look at the number of hurries for all of the Texas defense and compare that to the other stats you've seen. They are much different. For example, Orakpo alone actually has 21 according to
link which is texassports.com. The whole Texas team has 94! 94! Their opponents have 8. FSU as a team has 8. Seems a bit skewed. JMO
I don't think FSU does because of how often we blitz. Practically every passing play is a hurry. We blitz like 85% of the time, it's just the Mickey Andrews style of defense. You'd just be giving hurries every pass play. It'd be pointless.
Teams calculate stats differently.
Some teams may count every tackle on the quarterback behind the LOS as a sack, but I know other teams do not, like FSU and GA Tech. If it's a designated QB run then they only count it as a TFL. It's happened numerous times this year.
I go mostly by what I have seen when I watch the teams, and I would say that Orakpo should be higher rated than Brown and he should be the highest rated DE.
Michael Johnson is really not impressive IMO.
