I think that people are forgetting things, with the exception of TT's spread offense, all the other spreads are starting to slow down with the numbers they put up. Look at UF, WVU, hell, look at every spread team in the nation with the exception of TT where the real spread was pretty much invented.
First off, the spread has been run long before Leach went to Texas Tech. It pretty well has it's roots from LaVell Edwards and BYU in the 70's and 80's. Where did Leach graduate? BYU.
Leach has added a little here and there, and is more aggressive with it than many, but it hardly started at Tech, or even within the last decade for that matter.
The spread is the most overused term in football today. Leach offense is completely different than Urban Meyer's who's is completely different than Rich Rodriguez's, which is completely different from Missouri's. They may have the similar concept of forcing teams to defend the whole field and tackle in space, but so did Osborne's power running\option attack for that matter, and Johnson's option attack which aren't very similar either, yet get lumped together as option football.
