Not a single excuse, actually. There's no denying those guys are on the roster. You asked whether or not it indicated a discipline issue, not whether we had guys with a lot of suspensions on the roster. There are no 'special rules.' I just expect you to know the difference between an undisciplined player and a reclamation project. Jerry likes his reclamation projects. He's said it publicly, and made a big deal about investing in it. It shouldn't be a surprise to anybody that there are a lot of suspended games on the roster as a result.
That said, I'm not against giving these guys chances. The only thing I'm against is spending draft picks on troubled players or giving them big contracts we can't get out of easily. As long as we avoid both, if we dedicated one roster spot/year to one of Jerry's kids, I'm ok with that. You get a year like we got out of R. McClain in 2014, and it's generally worth it.
As for your final comment, that's a good point. If we're tops in the league in Garrett's whole tenure (basically since 2011), excluding Jerry's misfits, I'd say you have a point.
