A long time ago I read that to gain any benefit for position practice, (hands, tackling, blocking, etc), you needed to put in at least 7 minutes, also that anything over 20 to 23 minutes didn't add value. Can anyone say whether or not this has changed? In playing around with my practice times I let the computer select, (meaning I set the quarterback to pass, runningback to speed, etc), the defaults filled in the times for each position and I got times anywhere from 1 min to 49. Do the smaller or larger times hurt or benefit each skill? Thanks
