The ending of the classic Kevin Smith movie "Clerks" features Dante, the protagonist of the story who got tricked by his boss into working a 16-hour shift at a convenience store on his day off, lamenting to his friend Randall that, "I'm not even supposed to be here!"
That same verbiage with an opposite sentiment can be used to describe many of the best waiver picks this week. These players weren't supposed to be in the advantageous situations they are currently in, and their change in fortune can offer significant help to those fantasy owners who put in claims for them.
Alex Smith (available in 90.7 percent of ESPN leagues)
Coming into the season, the story on Smith was that he was supposed to fill in as the starter until Colin Kaepernick, the 49ers' second-round draft pick, was ready to take over as the long-term starter.
Turns out that Smith might be keeping this job for a while. He ranks third in the league in passer rating (104.1) and has a 7-1 touchdown-to-interception ratio. One of the keys to his success is a 12.6 vertical yards per attempt (YPA) mark (vertical defined as aerials thrown 11 or more yards downfield). For perspective on that total, consider that only two passers (Aaron Rodgers and Michael Vick) posted a higher vertical YPA in 2010.
