The Texans waived him at the start of 2014 training camp, after Williams failed a physical.
In addition, the Texans waived the following 18 players from the roster: defensive end
"If you look at our roster, it looks good, but the bottom line is the guys aren't out there, so that's concerning for us as a team and me as a coach," Kubiak said last Thursday. "I love the way Newton has worked. I think he made a lot of progress as a player last year. He played hurt at the end of the year, which was tough on him and us as a team. We drafted a young man with a lot of ability (Williams). He hasn't been out here yet."
Newton is a former seventh-round pick who started 14 games last season before suffering a patellar tendon injury. Williams hurt his knee in minicamp in May.
"(Right tackle) is (a concern)," Kubiak said. "I think it is for the guys up front, too. Our four starters are locked in up front, putting Brandon in with those guys. I think even those guys are looking, thinking, 'OK, who's it going to be? Who's going to step up and take this job and play here for the next 10 years and play right tackle for the Texans?' So I think we're all watching that. I think Newton took a step towards doing that last year, and now he has to take another big step."
