I think the best bet for the Tech game would be the over, even without knowing yet what the total is but I would imagine it will be in the 60's.
The Cyclones aren't predicting a running game of any import from Tech, but for a 70 yard running TD that was disallowed (refs said the RB was out of bounds, the replay showed he wasn't) Tech would have had about 140 yards rushing last Saturday, and that's WITH Kingsbury getting sacked several times by the Wrecking Crew. Over the past three games (vs. North Carolina State, New Mexico and the Ags, the latter two on the road) Tech is averaging 140 rushing yards per game even without that missed yardage.
Tech has a DB that once intercepted Seneca Wallace twice while both were in the Cali juco ranks. Meaningless here, but a fun fact.
