tOSU tried a fullback at MLB and that turned out pretty well. If the safeties can play smart, and cover the 'blows' that aggressive CB's miss, then tOSU will be fine. If the CB's play 10 yards off the line, and let the WR's get a full head of steam up, then there will be some big gainers. Having said that, spread/flood formations put more pressure on the safeties than the CB's, because more to cover when the WR's get 'lost' in coverage. Hence the nickel and dime defenses, giving more backfield coverage. Ultimately, think tOSU will be fine, if the DL rises to the occasion and gets big pushes on the QB each and every play. That means hurries, and less time for the CB's and safeties to be in tight coverage. I like Ash's coverage theories, and expect tOSU to play tighter man this year. Got absolutely killed on the bubble screen last year, and opposition kept exploiting it, successfully. Second-and-short is a whole lot easier to exploit than having second-and-long for an offense.
Heck, this time of year everyone has a perfect won-loss record, and optimism abounds. Fully expect tOSU to be fine in the D, with the talent showing growth and savvy. Biggest problem will be getting all the stockpiled DB talent the reps to develop that savvy and cohesion.
