A string of surprising moves in Baltimore extended on Wednesday to a player who supposedly was safe.

Safety Bernard Pollard is out, and everyone is wondering why.

As one league source said in response to the news, “Three teams in how many years. Soon four. What does that tell you?”

Another source says that Pollard has a reputation for being outspoken, for complaining, and for drawing too much attention to himself. He wears on a team, with his talent keeping him around for a second year or third year.

More specifically, we’re now getting the clear impression that last year’s incident that, as reported by Mike Silver of Yahoo! Sports, was “practically a mutiny,” has contributed to the departure of Pollard — and could result in more players being purged.

And he’s where it gets really interesting. (Or at least less uninteresting.) Silver specifically mentioned Pollard and Ed Reed as instigators of the mutiny.

Coincidentally, we’re now getting indications that the Ravens don’t want Reed back.

So while coach John Harbaugh handled a difficult situation very well at the time (as evidenced by the team’s Super Bowl trophy), it looks like Harbaugh may have decided that, at the appropriate time, he’ll make sure it doesn’t happen again.
