Houston Texans defensive end Mario Williams, the No. 1 overall pick in the 2006 NFL draft, recently got a second opinion on his injured right foot by renowned orthopedic surgeon Dr. James Andrews. Williams has been nagged by a case of plantar fasciitis since before the season, but the opinion for now is that Williams will not require surgery, agent Ben Dogra said. "Dr. Andrews agreed with what the Houston doctors are saying, that he can't make the injury any worse and that it will heal on its own in time," said Dogra, acknowledging that his client saw Andrews within the past 10 days. "It's something that could change over the next few months, so we're going to keep monitoring it. Could he have surgery in the offseason? At this point no, but we'll see where it is in time." Sounds like good news. The Texans' up-and-down season, which has featured a pair of wins against the Jacksonville Jaguars and one against the Indianapolis Colts, leaves the franchise with many of the same questions as last offseason. The biggest issues: Is David Carr the long-term answer at quarterback, and is there a franchise running back on the roster? The Texans will get back former 1,000-yard rusher Domanick Davis from a season-ending knee injury, and they are hopeful that rookie offensive tackle Charles Spencer will be back to 100 percent after suffering a major leg injury early in the year. However, Carr's lackluster playmaking ability is what seems to have first-year coach Gary Kubiak most frustrated. Carr has a career-best 68.6 completion percentage, but his critical thinking and ability to get them into the red zone – perhaps best evidenced by a 1:1 touchdown-to-interception ratio – have not improved enough to warrant another 16 games. Does he know something about DD we don't know? Carr is owed nearly $12 million over the next two years, but there is speculation that owner Bob McNair will endorse either a trade or outright release between now and March 1. The team could turn to a veteran like Jake Plummer or Jeff Garcia in the offseason since both fit Kubiak's scheme. Second on Houston's offseason list is figuring out the backfield situation, although Ron Daynes late-season comeback is going to make it hard for a Mike Shanahan-taught staff to invest a top-five pick in a running back like Oklahomas Adrian Peterson. One thing hurting the Texans is a lack of a true identity. They need a veteran presence on the offensive line, as well as a safety that can make plays rather than just avoid making big mistakes. If they were to deal down in the draft, LSU safety LaRon Landry would fill that hole perfectly.
