The third-year passer knows that Tampa Bay is just two weeks away from making either Jameis Winston or Marcus Mariota the team's signal-caller of tomorrow.
Barring the draft being cancelled due to an angry invasion of extraterrestrials, Glennon's out of luck as a long-term starter on his current team. Who else could see their snaps chopped down by a rookie?
Let's take a look:
1. Geno Smith, Jets QB: Armed with the sixth-overall pick, Jets general manager Mike Maccagnan is open to trading up for Winston or Mariota. Coach Todd Bowles, meanwhile, is on the record saying New York wants to add another quarterback to compete with Geno and Ryan Fitzpatrick. Smith is a middling passer inherited by the new regime. This aggressive front office might not be done swinging for the fences.
2. Josh McCown/Johnny Manziel, Browns QBs: In his latest mock draft, NFL Media's Charley Casserly sees Cleveland trading with Washington to hopscotch the Jets and snag Mariota with the fifth overall pick. It's a real possibility. McCown is a placeholder, Manziel is a comprehensive wild card and the Browns already tried to swap for Sam Bradford -- twice. No team in the league is more desperate for a functional signal-caller.
3. Denard Robinson/Toby Gerhart, Jaguars RBs: After missing out on DeMarco Murray, the Jaguars still need help in the backfield. While Robinson "surprised" coach Gus Bradley with his frisky play last season -- and thoroughly outdueled the fading Gerhart -- look for Jacksonville to draft a runner earlier than some expect.
4. Zach Mettenberger, Titans QB: Team brass called Mettenberger their "poor man's Tom Brady," but the lip service out of Nashville rings hollow. The No. 2 overall pick is a rare asset. Under pressure to spice up this hyper-vanilla operation, Tennessee is a safe bet to grab one of the rookie passers barring a blockbuster trade for Philip Rivers.
5. Branden Oliver, Chargers RB: General manager Tom Telesco said last month that Oliver "can be a starter in this league," but the Chargers need to find someone who can duplicate the power Ryan Mathews brought to early-down snaps. Georgia's Todd Gurley and Wisconsin's Melvin Gordon are on the radar at No. 17.
7. LeGarrette Blount, Patriots RB: New England's postseason workhorse feels like a precarious long-term solution for the Patriots. After waving farewell to Stevan Ridley and Shane Vereen, look for Bill Belichick to draft help. One way or another, some dude we've never heard of will run for 235 yards and three touchdowns in Week 6.
8. Andre Ellington, Cardinals RB: Arizona's plans to give Ellington 25 to 30 touches per game never made sense. His 5-foot-9, 199-pound frame isn't built for workhorse duties, but he's the perfect complement to a between-the-tackles grinder. Everything changes in the desert if the Cards can pull off a swap for Adrian Peterson.
9. Dwayne Bowe/Brian Hartline, Browns WRs: With Josh Gordon nestled in absentia, Cleveland would be wise to use one of their first-round picks on a true No. 1 wideout. A physical, big-bodied target would keep Andrew Hawkins in the slot while pushing Bowe and Hartline down the depth chart, where they belong.
10. Justin Forsett, Ravens RB:Ravens director of college scouting Joe Hortiz told the team's official website that Baltimore wouldn't be opposed to drafting a running back in the first round. TheMMQB's Peter King also believes that Melvin Gordon "will not get past" the Ravens at No. 26. If he does, Baltimore certainly can live with Forsett after the fireworks he produced last autumn.
