Coaches have a lot on their plates, and one thing Kansas City’s Andy Reid can scrape off his is talking to Alex Smith about turnovers.

The former 49ers quarterback, whom the Raiders face Sunday, has thrown 283 passes since his last interception, the fourth-longest streak in NFL history.

“When he was at San Francisco, he was good with it,” Reid said in a conference call Wednesday. “He came here, he’s been good with it. He’s a smart guy. He understands that turnovers can hurt you.”

Smith swears he hasn’t thought about the streak, a big reason that Kansas City (6-5) has won five straight games.

“I didn’t even really know it was happening until this last week,” Smith said in a conference call. “The guys finally told me about it. It’s not something I’m thinking about at all. I’ll just continue to try to play good football, make good decisions and throw accurate balls to help this team win.”

Smith is 76 passes from breaking Tom Brady’s mark of 358 set in 2010.

Smith, often criticized for not taking chances downfield, was asked if not throwing interceptions is a skill.

“You’re touching the football every play as a quarterback, and that comes with a lot of responsibility in executing the offense,” Smith said. “You focus on what it is you’re trying to do. You try to make good decisions, play fast, throw the ball accurately and get it to your playmakers, that’s what you’re thinking about, really.”

In the past eight games, Smith has completed 164 of 256 passes (64.1 percent) for 1,957 yards with eight touchdowns and no interceptions.

Reid says it’s all about developing good habits.

“I think it comes more down to you’re not thinking about the interception, you’re thinking about that completion,” Reid said. “Then the time that he spends working on execution and studying tape and doing those things I think adds up into limited turnovers.”

Smith said he is comfortable, whereas there have been times in past years when he has weighed being careful against being too careful.

“I feel like we go out there to make plays and score points and that’s the mind-set,” he said. “In doing so, there’s a way of going about your business as a quarterback, when you touch the ball every play, you get a lot of responsibility. You can’t be careless with it. But, you know you’re going out there to score points as an offense.”

One thing that’s really helped that goal is the addition of free-agent Jeremy Maclin. The former Eagles receiver has 57 catches for 772 yards and three touchdowns.

“I would probably compare it to what (Michael) Crabtree has done with” Raiders quarterback Derek Carr, Reid said. “It’s the same type of thing. It’s someone he can trust and has seen quite a few snaps on the football field.”

Crabtree, like Smith, played for the 49ers. Smith, traded to K.C. in March 2013, was asked if he had any reaction to San Francisco’s off-the-cliff season.

“No, no,” he said. “I’m so far removed, I’ve got nothing.”

Tuck honored: Raiders defensive end Justin Tuck, out for the season with a torn pectoral, was nominated for the NFL’s Walter Payton Award, for excellence on and off the field. Through his and his wife Lauran’s R.U.S.H. for Literacy program, the Tucks provide Alliance Academy in Oakland books and reading materials.

They also worked with upcoming Super Bowl 50’s “50 Fund” to strengthen literacy-enhancing programs that increase third-grade reading proficiency throughout the Bay Area. The Tucks donated $250,000.

Injury update: Center Rodney Hudson (ankle) and linebacker Neiron Ball (knee) didn’t practice Wednesday, but there were some whispers that Hudson would return Thursday in hopes of playing against his former team on Sunday.
