By the time you read this, Michael Sam should be back up in Canada singing “Alouette, gentille alouette!”  About a week ago, Sam’s football career all but flatlined as he abruptly left training camp with the Montreal Alouettes for “personal reasons”.  He was suspended and local reporters mused that he wouldn’t be returning.  The team’s general manager was perplexed.  “He wanted to go home, and that’s what he did.  I don’t know why.  When a guy wants to go home, they go home.  He had some personal things to take care of.  I wouldn’t be surprised if he returns.  I’m surprised he left.  I was very surprised.  If he doesn’t come back, I would think football’s over for him.”  Rumors circulated that he wasn’t doing well in practice and had trouble with his teammates.  While we still don’t know anything about his mysterious departure, Sam was expected to return to practice on Monday.
