The Seahawks don't run a ton of 'college' style plays outside of a few basic read option plays and the Percy Harvin jet sweep, but with an upcoming season where Harvin will ostensibly be healthy, it might be worthwhile to learn about some of the wrinkles the college game is doing with the read-option and with sweeps.
FishDuck.com is dedicated to Oregon football (sorry Husky fans) and they do some really excellent work on X's and O's breakdowns.
Here's Charles Fischer explaining the Jet Lead Fly Sweep out of the triple option look. This may or may not be a wrinkle we could see the Seahawks implement next year, particularly as an option for Harvin to motion into the backfield and use one of Seattle's runningback/fullbacks to lead block.
Either way, it's interesting, well explained and illustrated.
