On HoustonChronicle.com: Matt Schaub’s tumultuous tenure with the Texans could be coming to an end. Texans beat writer Brian T. Smith breaks down the quarterback’s situation.

A look at Matt Schaub’s roller-coaster, bittersweet seven-year tenure with the Texans:

* March 2007 – Texans acquire Schaub in a trade with the Falcons, giving up their second-round draft picks in 2007 and 2008, and release David Carr, their first-ever draft pick and the starting quarterback for the franchise’s first five seasons.

* September 2007 – Completing more than 70 percent of his passes, he wins his first two starts as the Texans beat Kansas City at home and Carolina on the road.

* September-December 2007 – The Texans lose seven of his next nine starts before an injury to Schaub’s non-throwing shoulder keeps him out of the final four games of the season.

* September 2008 – He gets off to a terrible start, throwing five interceptions in his first two games as the Texans, disrupted by Hurricane Ike, go 0-2.

* October-November 2008 – An intestinal bug keeps Schaub from playing in the season’s fourth game against Indianapolis at Reliant Stadium, then a knee injury suffered in a week-nine loss to the Vikings costs him four starts.

* December 2008 – He directs the Texans to three victories in their final four games, including a win at frigid Green Bay when he throws for 414 yards and two touchdowns.

* September 2009 – After being upstaged by Jets rookie Mark Sanchez in the season-opener, Schaub throws four touchdown passes for the first time in his career in a dramatic victory at Tennessee.

* October 2009 – He again throws four touchdown passes in a victory at Cincinnati.

* December 2009 – After a four-game losing streak seemingly dooms the Texans’ playoff chances, Schaub leads the Texans to a closing four-game winning streak as the team finishes with a winning record for the first time, missing out on a trip to the post-season when the Jets win on the final night. He leads the league in passing yards and completions and earns his first trip to the Pro Bowl.

* February 2010 – He’s named Most Valuable Player in the Pro Bowl.

* September 2010 – Schaub throws for 497 yards and three touchdowns in leading the Texans to an overtime victory at Washington.

* November 2010 – As Schaub throws only four touchdown passes over an 0-4 span following a 4-2 start, the Texans never recover and wind up finishing 6-10.

* November 2011 – The Texans go 7-3 behind Schaub, but his season comes to an early end when he suffers a Lisfranc foot injury on a quarterback sneak at Tampa Bay. He watches rookie T. J. Yates lead the team to the playoffs for the first time, defeating Cincinnati in the wild-card round.

* September 2012 – After helping beat the Dolphins in the season-opener, Schaub gets a four-year, $62 million contract extension, binding him to the Texans through 2016.

* October 2012 – A week after faring poorly in matchup against Green Bay’s Aaron Rodgers in a 42-24 loss, he leads the Texans to a 43-13 rout of the eventual Super Bowl champion Baltimore Ravens, throwing for 256 yards and two touchdowns.

* November 2012 – After passing for 527 yards in a victory over Jacksonville to tie Warren Moon for second most in a single NFL game ever, Schaub outduels Matthew Stafford in Detroit on Thanksgiving Day, then leads the Texans to another win at Tennessee, his 15th victory in a span of 16 starts.

* December 2012 – He plays poorly in a humiliating 42-14 Monday night loss at New England, then stays in a personal slump as the Texans also lose two of their final three games.

* January 2013 – Schaub starts and wins his first-ever playoff game, but the Texans win more on the strength of their defense than his offensive productivity. Returning to New England the following week, he again comes up short against Tom Brady.

* February 2013 – Schaub makes a second Pro Bowl appearance.

* September 2013 – After the Texans fall behind 28-7 at San Diego in the season-opener, he orchestrates a dramatic fourth-quarter rally as the Texans win on the final play with a field goal, then the Texans beat Tennessee in overtime the following week in Houston on his touchdown pass to rookie DeAndre Hopkins. But the Texans fail to score a touchdown at Baltimore in the third game and, after manhandling Seattle’s Super Bowl-winning defense in the first half of the fourth game, they collapse late to lose in overtime. Schaub’s third pick-six in three games, returned 56 yards by Richard Sherman, had let the Seahawks tie the score in regulation.

* October 2013 – He becomes the first NFL quarterback to have an interception run back for a touchdown in four consecutive games when his first pass in San Francisco gets picked. Schaub throws two more interceptions later and the 49ers romp 34-3. Returning to Houston, the Texans are again routed, 38-13 by St. Louis, and he suffers a leg and foot injury on a fourth-quarter sack. As he’s being tended to, Texans fans roundly boo him. Coach Gary Kubiak announces three days later that Case Keenum will start the next game at Kansas City.

* November 2013 – Keenum starts the next three games, too, but Kubiak sends Schaub out for the fourth quarter against Oakland with the Texans trailing 28-17 and Keenum struggling. Schaub directs field goal drives on his first two series but the Texans don’t score again. After his final pass falls incomplete on fourth down at the Oakland 8, he charges after Andre Johnson, the intended target, and screams at him in full view of the fans. Johnson later owns up to having run a bad route on the play.

* December 2013 – Schaub again replaces an ineffective Keenum in the third quarter at Jacksonville and directs drives that produce a field goal and a touchdown. But he throws an interception with just over two minutes left to end the Texans’ last chance for a comeback victory. It’s the team’s 11th consecutive defeat and Kubiak is fired the next day. Interim coach Wade Phillips announces Keenum will remain the quarterback for the rest of the season, but a thumb injury shuts him down with two games left. Schaub returns to the lineup, throwing four interceptions against just a single touchdown pass as the Texans finish with 14 losses in a row.

*March 21, 2014 – Matt Schaub is on the verge of being traded to the Oakland Raiders. Here’s a full story.
