It really depends. Say you have "too much usage" with 90 Jordan, 10 James, 92 Rodman, 11 Howard & 67 Wilt.
In a normal amount of minutes, there's no way everybody gets their RL touches. Yet in a playoff series, if you pumped up everybody's minutes to 48, the chances of you hitting the individual possession penalty on anybody would be much lower. The chances that everybody gets their touches would be higher (but I don't think it'd hit it with that group - we're talking about 24.5 usage points).
It really just depends on everyone's usage tier and the normal amount of minutes they played. If someone only played 24 minutes a game, I'm pretty sure you couldn't keep them from getting too many touches while playing them 48. If they played more than 36 a game, then yeah, I think it's possible. Keeping that in mind, it can be a reason to draft "too much usage" so that come playoff time, the likelihood of anybody hitting individual possession penalties is lower when you're playing everyone extra minutes. That being said... you might not make the playoffs if you waste too much bank on too much usage. It can be a very valid strategy for stupid high cap leagues (the ones noobs make that are $70+ million)...
One game, play everybody 48 minutes. Then sit everyone and play another group 48 minutes. If you've got upwards of 18 or 20 usage points, this strategy could work. Again, though, this is only for the really, really high cap leagues.
