not sure if i understood you right, dave, but my understanding of the FB is that you can run normal tempo or uptemp, but cant run slowdown
jag... i beat my head against that wall for about 40 seasons at tark cuse. had some success at times, but ALWAYS felt it was in spite of FB/press.
im assuming you already get that you have to have depth and stamina.... if you didnt have quite enough depth and or stamina, you would welcome folks to slow the tempo so your dudes wouldnt wear down quite as much. but, since you are frustrated by opponents slowing the pace, i assume you feel, as i did, that fb/press does not allow you to wear the other team down to the extent you would expect (when they do slow)
i always had the feeling fbpr was a bit of a crapshoot... could lead to huge blowout wins or great upsets, but defintely resulted in more headscratching losses than the other offenses. so, in the end, we genrally had great regular season teams... but found it very tough to stringtogether 6 wins in postseason. plus, it was way more difficult imo to put together a program that was top20ish every single year... especially in d1 with EEs, you just HAVE to have that depth and stamina and there's gonna be at least one or two seasons out of every four where you are just to inexperienced and thin to be an NT contender.
to answer your question i think it depends wether uptempo will wear you down at all (if so, dont do it) and how much it will wear down your opponent or allow for foul trouble. i agree that uptempo doesnt wear them down as much as we would hope, but it will wear them down a little and allow for more possession adn more foul trouble,,, so if thier bench is thin-ish or they really rely on a few stars, id still go uptempo
good luck with the fastbroke ;-)
