From Comcast SportsNetSANTA CLARA, Calif. (AP) -- Alex Smith is trying to understand how he lost his job as starting quarterback of the San Francisco 49ers a month after being named NFC Offensive Player of the Week.It's not an easy thing for the NFL's fifth-ranked quarterback to deal with this week, even though Smith already has experienced plenty of ups and downs in his tumultuous career since the 49ers made him the No. 1 overall selection of the 2005 draft.Smith spoke with the media Thursday for the first time since coach Jim Harbaugh made Colin Kaepernick the team's starting quarterback for Sunday's game against the St. Louis Rams, a rematch of the last game in which Smith appeared.Smith is now completely healthy from the concussion he suffered in that Nov. 11 game and has been medically cleared to play.But he'll be Kaepernick's backup for the second consecutive week. Smith is uncertain what Harbaugh's decision means for him the rest of this season."I feel like the only thing I did to lose my job was get a concussion," Smith said.Smith was playing some of the best football of his career when he was injured and left early in the second quarter of the 24-24 tie with the Rams.He completed 7 of 8 passes with a passer rating of 143.8 against St. Louis, throwing for his 13th touchdown of the season on his final pass. The week before, Smith completed 18 of 19 for 232 yards and three touchdowns during a win over Arizona, setting an NFL record with a 94.7 completion percentage for a quarterback with a minimum of 15 attempts. He was named NFC Offensive Player of the Week for the first time two days later.Smith ranks fifth in the NFL with a passer rating of 104.1 and leads the league with a 70.0 completion percentage."You kind of state your case with your play and I felt like I've done that," Smith said. "It's tough. It stings the most just because I really felt there was something special going on here and you sacrifice and invest so much time. I felt like I was playing good football. I have no idea what's going to happen from here. All I can do now is just prepare and get ready."Smith was in limbo the past two weeks after suffering his concussion, practicing every day with the 49ers in a non-contact black jersey. The 49ers did not announce during either week who would be their starting quarterback until game day against Chicago on Nov. 19 and New Orleans last Sunday.There's no uncertainty this week. Kaepernick, San Francisco's second-round draft pick last year, took away the starting job from Smith with strong performances in decisive victories over the Bears and Saints.Smith has lost his starting job and dealt with injuries and adversity several times before with the 49ers. He was beaten out for the role in training camp in 2008 by journeyman J.T. O'Sullivan, then began the 2009 season behind veteran Shaun Hill before starting the final 10 games of that season.In 2010, Smith was replaced as the starter by former coach Mike Singletary with Troy Smith for a key December game that decided San Francisco's playoff fate that season. The next week, Alex Smith began a string of 28 consecutive starts for the 49ers that ended after his concussion.Smith had a 21-6-1 record in those games and played a significant role in San Francisco's rise back to prominence last year and continued success this season. Smith resurrected his career under Harbaugh, who took over as San Francisco's coach in 2011."Those (other seasons) are all in the past," Smith said. "For this one, you're in it right now. It's such a great team, such a great group of guys in this locker room. There's something special going on. It's a tough pill to swallow, for sure."Smith said he was prepared for Harbaugh's decision and knew it was a possibility "just based off the last couple of weeks the way things have gone." Smith got the news during a conversation with Harbaugh earlier this week, when the coach explained why he decided to go in a different direction.Harbaugh left open the possibility he could go back to Smith at any time."Alex is a class act all the way," Harbaugh said. "He'll prepare as if he is the starter. And that's what we would expect. And be ready to go in and play and contribute to this football team. We've got two quarterbacks that we feel great about as the starting quarterback. Anything's a possibility. I would assume nothing, or rule out anything."Smith said he felt no resentment toward Harbaugh, nor did he try to talk the coach out of the change at quarterback."At this point, what's talk going to do?" Smith said. "I feel like he made up his mind, and he's not a guy that didn't put thought into it already. I don't get to make those decisions. That's what he gets paid to do. I play football. So that's what I'm going to continue to do. Continue to get ready, and then make the most of my next opportunity."
BOSTON – Here are a few odds and ends to keep an eye on heading into tonight’s game against the Sacramento Kings:
· The Celtics have won eight in a row over the Kings in Boston, with the last loss to Sacramento at the TD Garden coming on Jan. 19, 2007. Current Celtic Gerald Green was in the starting lineup that night.
· Only six times in franchise history have the Celtics launched 38 or more 3-pointers in a game, four of which came in the month of November this season.
· Speaking of 3-pointers, 36.2 percent of Boston’s shots are 3s. That ranks fifth in the league behind Houston, Cleveland, Brooklyn and Golden State.
· Don’t be surprised if Avery Bradley gets off to a good start tonight, especially from 3-point range. He’s shooting 59.1 percent on 3s in the first quarter which ranks second in the league.
· Isaiah Thomas tallied 395 points scored in November, the most by a Celtic since John Havlicek had 406 points in November during the 1971-1972 season.
· Boston leads the NBA in points scored (46.3 per game) by second-round picks. The Celtics’ second-round picks include Isaiah Thomas; Jae Crowder; Amir Johnson; Jonas Jerebko; Demetrius Jackson and Jordan Mickey.
· The Celtics are 5-0 this season when they outrebound an opponent.
· Tonight’s game will be Boston’s fifth set of back-to-back games this season. In the first game, they are 3-1 this season. On the second night, they are 2-2.
BOSTON – When it comes to defense, the Celtics are quick to claim that it is indeed the foundation for which their team is built upon.
Still, far too often this season, we have seen cracks in their usually Teflon-tough defense, the kind that ultimately means the difference between winning and losing.
The Celtics’ defense will once again need to step up and play well tonight against a Sacramento squad that has shown it can fill it up offensively of late.
Sacramento (7-11) has scored 100 or more points in eight of their past 10 games. In that span, their 107.2 points per game ranks ninth in the league.
In that same span, the Celtics have allowed opponents to score 100.3 points per game, which ranks 10th in the NBA in fewest points allowed.
And when it comes to winning, limiting teams to less than 100 points has been huge in Boston’s win total.
The Celtics have held eight opponents to 100 points or less this season.
Their record in those games? 8-0.
Within that limited scoring, Boston must also make sure teams don’t get into a nice groove shooting the ball.
Boston is 0-5 this season when an opponent shoots 48 percent or better from the field.
While there are several things Boston must do to be successful, having the right kind of defensive disposition ranks at or near the top of that list in their efforts to play with the kind of defensive success that gave so many hope that this would the year Boston would hold court among the top teams in the Eastern Conference.
“We have to get a little more nastier on the defensive end and not let a team come in and get comfortable,” said Boston’s Jae Crowder.
