Mike Smith is one of the best all-around runners in the NFL.
So it was no surprise that he started running a lot more in the offseason.
The 49ers defensive back is one-third of the league’s leading tacklers with 15.5 tackles for loss, according to Pro Football Focus.
But it’s also been an incredible fall from grace.
Smith was arrested in December on a charge of domestic battery after an argument over a $2 bill in the car that Smith had borrowed.
He pleaded not guilty, and after a month-long trial, the judge found him not guilty.
When he was arrested, Smith said he didn’t do anything wrong, according the Associated Press.
But Smith’s arrest was a setback for a career that began with a spectacular rookie season in 2015.
He was one of two NFC rookies to break out of the second-team offense and into the starting lineup in 2016.
He recorded a career-high 6.5 sacks in 2016, and in 2017, he recorded a sack, interception, and forced fumble.
In 2016, Smith was named to the Pro Bowl and played in three Super Bowls.
He led the league with eight interceptions and was a key contributor to the 49ers’ championship run.
He finished with a team-high six sacks in 2017.
He’s had to put it all together again in 2017 after missing a chunk of the season due to a torn ACL.
He returned in Week 5, but the injury kept him out of action for the next three weeks.
He started the season with a shoulder injury, but after a few weeks he was cleared to play again.
In Week 4, Smith played in every game, including a Week 5 win over the Houston Texans.
He added four tackles, two passes defensed and a forced fumble, while also recording two sacks.
He missed the final five games of the year with the injury, and by Week 13 he was back to the starting 11.
But by Week 14, he was sidelined for two games.
Smith started in the second half of the 49er’s Week 15 win over Green Bay.
He posted four tackles and an interception.
After the game, Smith told reporters he was feeling “great,” but that the injury would take its toll on his season.
Smith has played through injuries before.
In 2017, Smith missed two games due to an ankle injury.
He made the 53-man roster in Week 16, and he missed the entire 2018 season after undergoing surgery on his right knee.
After a strong season, Smith became one of his team’s leaders in 2017 and was named the team’s Most Valuable Player.
He won the NFL Defensive Player of the Year Award in 2018.
The 49ers had a promising start to the season.
They went 9-5 and went to the playoffs for the first time in two seasons.
But they were still without their franchise quarterback.
Smith had surgery on a torn meniscus in the final week of the regular season, and missed the first eight games of his 2018 campaign with the knee injury.
In 2017, the 49, the reigning Super Bowl champions, won the NFC West title.
They also made the playoffs with a 4-1 record, but lost to the Seahawks in the first round.
They finished the year ranked seventh in total defense, but were fourth in passing yards allowed.
