Thankfully, Harvin and his insane speed are gone. They still have stockpiles of it but he could hit a go pattern nearly every play last year if you didnt watch out for it.
OSU loses Wells and a few of their WR's. Im sure they reloaded for the most part though. I enjoyed having Todd Boeckmen (sp) to use in passing situations where I knew I didn't need to scramble. This will potentially hurt OSU if ACC matters.
