The Greg Hardy and Scandrick reduced suspension should make it less than 100 games.
Substance(s):

16 - Randy Gregory

4 (2) - Orlando Scandrick
Not substance(s):
10 (4) - Greg Hardy
10 - Josh Brent
Hardy's and Scandrick's reductions adds up to 92 games. McClain's further suspensions were incurred after Dallas was planning on releasing him, so that should be -16 more.
Dallas was clean with substance/PED suspensions from 1999 until 2014. Something might have happened in 2013 to lower their standards. Maybe a historically bad defense.
