I hate to say it, but I think speed may have been a factor in the last two NC losses. Not tOSU's speed, nor Florida's or LSU's, but their opponents.
This is obviously my opinion, and I have a couple of elbows and one @ssh&*^ as well
but I think the level of competition Florida and LSU played better prepared them for the NC games. The B10 has been down some the last few years (remember, my opinion) mainly because Iowa's swoon and the inability of scUM and State Penn to develop their talent.
The "big" non-conference match-up last year, UW didn't do much to prepare the Bucks for an elite opponent (damn that Ty Willingham) and even against Texas the season before, the Longhorns were much, much less daunting without VY (seems like Mack Brown is not over the great recruiter, so so coach issue yet)
I just felt like tOSU (coaching staff as well) was not as prepared to face a team just as talented, deep and fast as what the Gators and Tigers were, having faced tougher competition in the regular season. I think the coaching staff needed to step out of their comfort zone (play smart, don't beat yourself, let the other team make the mistakes) and take some chances (specially on D)
I may be all wet, as I've only watched both NC losses only once (couldn't stomach more) and those memories were tempered with spirits
but it seemed to me Tressel ball worked against a Miami team that made more mistakes, was extremely arrogant and overconfident and not overly well coached, but obviously did not work the last few seasons in the biggest of games. Maybe tOSU will win a couple of NC's in the next few years playing Tressel ball, but relying on a team just a talented and deep, and maybe as well coached to make mistakes to get the win may not be the way to go.
I am not trying to imply that I am down on the coaching staff, just that they need to learn and grow, (and I think they will) and also that the idiots in the media that chalk the losses up to lack of speed and athletic ability are more stupid than I ever imagined, if that is theoretically possible.
I would also like to add kudos and agreement to whomever (I believe a politician) said that if he ever needed a brain transplant, he wanted a reporters brain, because he knew it was brand new and had never been used.
