I'm with Brandon on this one. It was dangerous and reckless. It could have caused someone serious injury or death. Luckily (very luckily), it didn't.
I don't know what the appropriate suspension is. Ultimately, this just can't happen again. If his embarrassment and shame is enough, so that he never drives impaired again, then I guess one game is enough.
We'll see if the league does anything further.
Since the accident, from a Blue Bombers point of view, he has done everything correctly. Contacted them immediately and faced his teammates as soon as they were gathered, and met with the media. If they can forgive him, then I expect this not to become a distraction.
