Should Bills worry about Mario Williams?

There is some disturbing news coming out of Buffalo this weekend, where text messages from star defensive end Mario Williams were released by his ex-fiancée's attorney. Williams is currently in a legal battle over an engagement ring worth more than $780,000, and new details emerged that Williams allegedly had "dramatic mood swings” last year during their engagement.

"No money in the world should leave me with suicidal thoughts," Williams said in the text to his ex last November.

In another text Williams said, “I need to go back n my shell. There's no telling what Ill do to myself at this point. I'm sry Ill disappear from now on."

Should the Bills be concerned about Williams?

Buffalo invested $100 million in Williams and made him the highest-paid player in franchise history. He had an up-and-down first season with the Bills in 2012 but still led the team with 10.5 sacks. Williams dealt with a nagging wrist injury and apparently wasn’t in the best frame of mind at times last season because of issues in his personal life.

Lawsuits can get ugly when they involve former lovers, and it appears this is one where no punches will be pulled. Williams recently wrote a Twitter message assuring everyone that he is fine.

"I'm still here and always will be," Williams tweeted. "I'm too strong for ridicule and the childish extremes those will do to try and taint a person’s name when in reality you make me stronger, hungrier and more determined."

The best thing Williams can do at this point is prove he's ready to move on with his life. A big year on the football field in 2013 certainly can help in his recovery while also boosting Buffalo’s stock. That would be a win-win for Williams and the Bills.

This is a tough thing for Williams to go through, especially when details of his personal life are being released to the public. Maybe the Bills should have a brief talk with him just to make sure everything is OK. The Bills are counting on Williams heavily this year, and he needs to be sound physically and mentally.
