Bills: Mario Williams ready to face his former team in Houston

Mario Williams is happy to be with the Buffalo Bills. But the defensive end is not exactly thrilled with how his time with the Houston Texans ended.

Williams will square off against his former team for the first time Sunday, and he discussed his departure from the Texans in detail Wednesday for the first time since signing in March.

After six productive years in Houston, the former No. 1 overall pick said he was never given a contract offer from the Texans -- contrary to some reports -- giving him no choice but to leave in free agency.

“It's a decision that the general manager made,” Williams said. “Opened the door and pretty much gave me a one-way exit and that was it. At the end of the day, it is what it is. It's part of the business. People don't realize really what happened at that point in time and that's fine. The fans can only go off of what they hear everybody else say.”

Williams knows he may not get a warm reception Sunday, acknowledging he'll probably be booed by Texans fans. But he doesn't want Texans fans to feel like he abandoned them for the highest bidder.

“It's the simple fact that everybody looks at it as you just up and leave, but you don't know the fact of basically being told, you know, we're not giving you anything as far as an offer or anything like that,” he said. “Your hands are tied in that aspect and everybody else looks at it like you just went in free agency and left. Obviously, there was plenty of time for things to get done that it wasn't and that's fine with me. I just wish everybody else who runs their mouth and says this and that knew the whole story about it before making a decision about me just abandoning fans or the team or anything else like that. That's not my role. I'm not that type of guy.

“I'm sure everybody's going to twist it and say, ‘He didn't want to come here' [to Buffalo] and so forth -- that's not what I said. Like I said, I never asked to leave. I was basically given the door in a quiet manner and I had no other choice.”

In hindsight, it looks like the Texans may have made the right decision. Williams received a six-year, $100 million deal from Buffalo -- the highest contract for a defender in NFL history -- and has been a disappointment through seven games (16 tackles, 3.5 sacks). The Bills (3-4) are 31st in yards allowed, last in points allowed and last against the run. The Texans, meanwhile, boast the best record in the AFC (6-1) and are third in total defense.

Williams knows there's no better week to turn it around.

“At the end of the day, I have something extra to prove in general,” Williams said. “Definitely with everything that's been going on it hasn't been the way I really wanted it. [I want to be] going out and making an impact and just helping this team win.”
