If the two-QB fantasy league you are in is competitive at all, rookie passers Teddy Bridgewater of the Minnesota Vikings and Blake Bortles of the Jacksonville Jaguars were snapped up off the waiver wire. Hopefully you have a QB that's starting that you can throw in there, but depth is crucial. With that said, here are two sneaky stashes that may pay off later this season.

Zach Mettenberger, Tennessee Titans

After an impressive showing in Week 1, in which Titans QB Jake Locker threw for 286 yards and two touchdowns in an upset victory over the Kansas City Chiefs, Locker has regressed.

Over the next two games Locker's tossed four interceptions against a single touchdown in back-to-back losses. He's yet to eclipse 300 yards through the air in 2014, and he's accounted for just 73 yards on the ground.

For fantasy owners, the rushing numbers were what they counted on. Locker is one of the best pure athletes at his position, and his ability to pick up yardage on the ground filled in what was left to be desired by his passing totals. The rushing isn't there though, and his passing has shown no improvement.

The Titans could be in for another long Sunday when they travel to Indianapolis. Andrew Luck's been the NFL's best quarterback statistically through the first three weeks, and Locker may not be able to compete in a shootout. There's no telling if rookie QB Zach Mettenberger can either, but it may not be long before he's given a shot.

The fifth-round pick out of LSU fell in the draft because of a torn ACL suffered late in his season, as well as a flagged drug test at the NFL Combine. During his final season on the field though, Mettenberger was among the top passers in the SEC. He threw for 3,082 yards, 22 touchdowns, and only eight interceptions.

The running game could improve once the coaching staff hands entrusts rookie running back Bishop Sankey with more of the workload, and the Titans' weapons in the passing game are impressive. Pick up Mettenberger if there's room to spare, and patiently wait.

Matt Moore, Miami Dolphins

Ryan Tannehill has been middling in three starts for the 1-2 Dolphins, and head coach Joe Philbin is dropping major hints that Tannehill may need to take a seat unless his play improves.

When asked if he'd bench Tannehill for backup Matt Moore Philbin responded, "I think I just answered the question. That's what we are going to do. We are going to get our 46 best players to the game and we are going to utilize them the best way possible."

Tannehill's numbers are pedestrian for sure, but aren't disturbingly bad. He's found his rhythm with No. 1 wide receiver Mike Wallace, but the offense has struggled to score points. Miami has scored 25 points combined in the past two games, which were back-to-back double-digit losses.

Moore will not be a magic cure for Miami's ills. He might be better than Tannehill though. His last run as a starter came in 2011; Moore started 12 games and threw 16 touchdowns against nine picks in that span. He averaged 192 yards per game, 16 less than what Tannehill has done so far in 2014.

This recommended stash is not meant for owners to think Moore will light the world on fire. He's an insurance policy if one of your two quarterbacks has gone down, or has a bye week later in the year. Any starting quarterback has value in the two-QB format, and Moore may soon be a starter.
