"2. 2013
1st round: EJ Manuel (No. 16)
2nd round: Geno Smith (No. 39)
3rd round: Mike Glennon (No. 73)
The Bills traded up for EJ Manuel and the former Florida State standout started 10 games as a rookie. Over the next three seasons, Manuel combined to start seven more, which should give you a clear indication of how little he progressed in Buffalo. He is now a backup in Oakland. Geno Smith was talked about as a first-round talent but he lasted until early in the second round. The plan was for him to eventually unseat Mark Sanchez, the Jets' 2009 first-round pick who had fallen out of favor in recent years. In a glaring case of "be careful what you ask for," a preseason injury sidelined Sanchez and Smith started all 16 games as a rookie. The Jets went 8-8 but Smith tossed 21 interceptions against just 12 touchdowns, and after going 3-10 in 2014 Smith was benched. Mike Glennon has the most remaining upside of this group but for how long is anyone's guess; signed this offseason to be the Bears' starter, the team promptly traded up in the draft to select Mitchell Trubisky with the No. 2 pick."
At least the 2007 draft class was ranked worse than 2013.
