McNair stopped short of saying he expected a Super Bowl win or appearance but did say before the season this was the most talented team in franchise history.
Quarterback has been an issue this season, as veteran Matt Schaub has struggled. When Schaub suffered an ankle injury in a 38-13 loss to the St. Louis Rams in Week 6, a smattering of home fans cheered. Schaub eventually lost his starting job to Case Keenum. On Thursday night, Schaub replaced a struggling Keenum in the third quarter.
McNair said during Friday's news conference that Keenum would be the starter for the rest of the season.
"Case is going to be the quarterback, and give him a chance to see how he can perform," McNair said. "Jury is still out. He's shown flashes of brilliance and then shown some rookie mistakes. Improve, eliminate those and continue some of the outstanding play, and see if he can be a starting QB in the NFL."
McNair also said that despite the tough season, the Texans expect a quick turnaround.
"We expect to be right back in playoff contention next year," McNair said. "This is not a long-term rebuilding process."
It could be argued that things started to go bad for the Texans last season. They entered a Monday night game at New England with an 11-1 record but were hammered by the Patriots 42-14. They lost three of four to end the regular season, then won a playoff game for a second straight season before losing again to New England in the divisional round, 41-28.
In addition to Kubiak, the Texans also terminated the contract of special teams coach Joe Marciano. The team promoted Bob Ligashesky from special teams assistant to special teams coach.
