Despite submitting arguably the best performance of Week 1, Kansas City Chiefs quarterback Alex Smith believes this season will be his last with his current franchise.

Smith revealed on "In Depth with Graham Bensinger" that he's getting the feeling the Chiefs are aiming to move on from him at the end of this year.

"For sure," Smith said when asked if 2017 feels like his last year with the Chiefs. "It absolutely does. Without a doubt."

Smith was dismayed by the Chiefs' decision to trade up 17 spots with the Buffalo Bills during the this year's draft to choose quarterback Patrick Mahomes II with the No. 10 pick.

Following the selection, many believed Smith would operate as a placeholder until Mahomes is ready to take the reins.

"It's a tough pill to swallow," Smith said. "It's like, man, (we) could've added this or this or this position or this player."

The quarterback also blasted the San Francisco 49ers, where he spent the first seven years of his career after being selected first overall in the 2005 draft.

Forget the coaching changes, I'm talking just the culture of the building was not (good). Unhealthy. Completely dysfunctional. Different people on different wavelengths, not a clear communication, not a clear goal of the entire building. Very separated. And I think that trickled into the locker room. We had a very separated locker room, offense, defense, special teams. It was not a selfless unit. Not everybody put the team first. I think all of those things that come with dysfunction that are the opposite of what healthy organizations and team enviornments have.

In any event, the 33-year-old certainly made a strong impression during Thursday's season opener, dissecting the New England Patriots by going 28-of-35 for 368 yards, four touchdowns, and no interceptions in a 42-27 win.

The Chiefs will certainly have to make one of their most difficult decisions in recent memory at the end of the season.
