I mean, it’s only a matter of time before Mangini’s gone, right?  Is there any way he’ll last the season?

On the same day that Browns running back Jamal Lewis said he thought coach Eric Mangini was working the team too hard, a Browns practice squad player named Keith Grennan ruptured his patellar tendon during an “opportunity drill.” Grennan, a second-year defensive end out of Eastern Washington, will have surgery Monday and will be out at least eight months. Grennan’s agent, Cameron Foster, confirmed the injury.

A source with direct knowledge of the incident confirmed that the injury happened during the “opportunity drill” period — a post-practice time when Mangini puts practice squad players and rookies through additional drills to give them the chance to impress coaches.

If someone badass like Jamal Lewis says the coach is working the players to hard, I’ll tend to believe them.  Lewis is a mean, mean dude – he’s like the antithesis of Shaun Alexander – so this isn’t a case of a wimpy player whining about practice.

The Browns are absolutely horrific and likely won’t win more than two this year.  If the players – like Lewis – are already turning on the Mangina, I just can’t see him coaching into next season.  Maybe it’s time to abandon the whole “coaching tree” philosophy of hiring and instead look for guys who actually know how to coach a football team.
