I just took over a new team who ran Man to Man defense. I am switching to Press defense. Do Player IQ's advance faster if I play press during games or do the IQ's only advance with Practice Minutes ? It will be a total loss season either way I just wondered if the players would improve faster if we actually ran the Press during games ? 

Yes, IQ will improve a teensy bit faster if you play it. That is, unless it's been changed. Hope that helps!

That's still correct. I switched this year from a combo defense to M2M only, but I still played press in a few games. My freshmen, who weren't practicing press at all, still saw a small bump in their press iq's from playing it a bit in games.

If there is a bump, it's extremely slight and not worth throwing away your season by playing press with a bunch of poor iq's. I would definitely play m2m until your press iq's catch up.

Thanks guys, i'll go back to the M2M ... I appreciate your thoughts... That is the way i've always played it in the past but wondered if I might be limiting improvement... 

players can improve in offenses/defenses without playing those sets, or playing against those sets.   It usually is only one letter grade from a F to D- or C- to C for examples.

I've seen no indication that playing a set will actually help the IQ improve quicker than not playing it.  Actually seble did mention in the test world that all IQs will slightly improve which contradicted the common belief in the forums that that F to D- bump was because your opponents played those sets.
