I'm not very well informed on the process but why is this an SEC decision? The article said the SEC has taken a stance on player safety with suspensions earlier this year. This would imply that each conference can set their own rules regarding player safety with some being more lenient than others. Also, there is the obvious conflict of interest part that the SEC would want their championship contender at full strength.
The Ncaa counts on every conference to step in and handle these sort of things, if not the ncaa will rein down hard on their decision if the conference does not step up. Of course in this decision had the NC game been the next game up for Bama, the sec probably would have suspended dial. Especialy after they had suspended the other two guys during the season.
