In 2013, the Kansas City Chiefs traded a second-round pick in the 2013 NFL Draft and a conditional pick in the 2014 NFL Draft to the San Francisco 49ers for Alex Smith.
As a result, Smith became the Chiefs' quarterback with the most regular-season wins (41) in his first four seasons in franchise history.
Only two quarterbacks, Tom Brady (47) and Russell Wilson (45), have more regular-season wins in that span.
Smith is entering his fifth season with the Chiefs, but his 13th in the NFL.
And he's got the numbers to show it.
Smith has beaten 30 NFL teams at least once in his career. The only two teams he has yet to beat are the San Francisco 49ers and Chiefs.
Only nine quarterbacks in NFL history have beaten 30 of the league's teams. Only two, Brett Favre and Peyton Manning, have beaten all 32.
Smith ranks No. 1 in Chiefs franchise history in yards rushing by a quarterback with 2,078.
For the second year in a row, Chiefs quarterback Alex Smith was voted as the league's 81st best player in the "NFL Top 100 Players of 2017" list.
And that's just to name a few.

At the NFL Annual Meeting in Phoenix in March, coach Andy Reid expressed how Smith is self-driven.
"He's the first one in and the last one out. I think everybody knows that he's in charge," Reid said. "I think he's just a good football player. Can he continue to get better? Absolutely. I think we just keep surrounding him with good players, and he keeps on going."
"I wish I had him as a rookie. I love him. I love how he goes about his business," Reid added.
Last season, Smith completed 328 of 489 passes for 3,502 yards, 15 touchdowns. He rushed 48 times for 134 yards and five touchdowns on the ground as well.
As expected, he also kept the mistakes to a minimum as well, throwing only eight interceptions.
One of the things you can credit Smith for doing well is getting the ball out quickly. Smith was among the fastest quarterbacks in terms of passing and getting the ball off and normally did a great job of evading pressure when it came his way.
There's no denying Smith is the leader of the team as he's led them to the playoffs in three of his four years with the Chiefs.
Ask anyone in that locker room and they'll tell you the same thing, and look no further than his numbers against teams within the division for why he's prepped to defend the Chiefs' AFC West title in 2017.
Smith is 15-7 against AFC West divisional opponents, including leading the team to 11 straight wins against the Chargers, Broncos and Raiders.
In those games, Smith has completed 64.2 percent of his passes with 32 touchdowns and just 12 interceptions.
