I'm a strong proponent of a high IQ team (maybe too much so, that's an argument for another day), but there have been many, many times where I've put 30 minutes into my O and D and left it like that for the season. In fact, with my Duke squad in Tark, I leave it 30 and 30 every season. To me, the way potential works now makes it easier to max your players ratings out with lesser minutes than before. That's just my opinion though, others will surely disagree with me. To each their own I guess.
