Fantasy: 10 deep sleepers for 2015

After presenting the players likely to break out and those who might bust, it's time to delve deeper and unearth some of the unknown commodities who could become fantasy relevant this season.

This is a list made up of players being selected outside of the top 150 picks. Most of the names mentioned are going undrafted and will be available on your waiver wire early in the year.

Depending on the size of your roster, you may want to use a late pick to stash them away, but if your league has a short bench, you can keep their names highlighted on your watch list. Just be ready to pounce if the stars begin to align in their favor.

Tyrod Taylor, QB, Bills

So far the Bills' quarterback competition is a wide-open race begging for someone to stand out. The veteran Matt Cassel has struggled and offers very little upside. EJ Manuel is not only in danger of losing out on the job, he also may need to worry about his roster spot. Taylor has had his ups and downs as well, but showed flashes of his talent through the air and on the ground. If he gets a chance to start, he'll be surrounded by a quality group of skill position players, and his rushing stats could allow him to make a fantasy impact.

Overachiever Potential: ★★☆☆☆
ADP: Undrafted

Buck Allen, RB, Ravens

Justin Forsett is a running back with one solid year under his belt who will turn 30 in October. That doesn't exactly inspire confidence for fantasy owners. There's a reason the Ravens used a fourth-round pick on Allen. The rookie is a solid receiving back and if he can prove his chops as a pass protector, he may steal snaps from Forsett. Allen will be a much bigger part of the offense than Lorenzo Taliaferro, if Forsett gets hurt.

Overachiever Potential: ★★★★☆
ADP: Undrafted

Christine Michael, RB, Seahawks

There are no guarantees Michael starts the year in a Seahawks uniform. It's possible he'll be the heir apparent to Marshawn Lynch, but it's equally possible Michael is released or traded prior to the season. The 24-year-old is a physically gifted runner who could deliver if given the right opportunity.

Overachiever Potential: ★★★★☆
ADP: Undrafted

Matt Jones, RB, Redskins

Alfred Morris can work on his pass-catching skills all he wants, but the Redskins aren't going to trust him in the receiving game. Jones is already getting reps as the third-down back, and if Morris isn't careful, the rookie might eat away at his early-down carries as well.

Overachiever Potential: ★★★★☆
ADP: Undrafted

Ahmad Bradshaw, RB, Free Agent

Bradshaw may not exactly fit the "unknown commodity" description, but he is well off the fantasy radar at the moment as he searches for a new team. The 29-year-old was a very capable back for the Colts last season and has reportedly been cleared for football activities after recovering from a fractured fibula suffered in November. Once he serves his one-game suspension for violating the league's substance abuse policy, Bradshaw will be back on the field.

Overachiever Potential: ★★★☆☆
ADP: Undrafted

Phillip Dorsett, WR, Colts

Dorsett appeared to be an unnecessary first-round selection at a position the Colts already had depth at. However, the lightning-quick receiver has impressed and may have the inside track on the No. 3 job behind T.Y. Hilton and Andre Johnson. If one of the starters is sidelined, the potential is there for Dorsett to experience a meteoric rise. Let's see how he looks in preseason action first, though.

Overachiever Potential: ★★★★☆
ADP: 16th round

Brandon Coleman, WR, Saints

The Saints need to restock their receiving arsenal after trading away Jimmy Graham and Kenny Stills. Brandin Cooks and Marques Colston will start, but the rest of the depth chart is fairly unproven behind them. Coleman has been forcing people to notice him, which isn't tough when you're 6-foot-6 and 225 pounds. Nick Toon is the final obstacle standing between Coleman and a consistent role in the offense.

Overachiever Potential: ★★★★☆
ADP: Undrafted

Kamar Aiken, WR, Ravens

Breshad Perriman was drafted to replace Torrey Smith in the starting lineup. The only problem is that Perriman hasn't been able to practice due to a knee injury. Aiken has shined in his absence and is currently listed as the starter. It's possible Perriman returns to the field and claims the job, but what if he doesn't? Aiken could find himself as a starting receiver in a very productive offense under new coordinator Marc Trestman.

Overachiever Potential: ★★★☆☆
ADP: Undrafted

Taylor Gabriel, WR, Browns

Gabriel is returning to his role as the Browns' downfield threat, however, very few fantasy owners seem to care. Maybe it's uneasiness over the quarterback situation in Cleveland. Perhaps it's worries about the state of the offense as a whole. Hopefully, it's not the presence of Dwayne Bowe and Brian Hartline. If Gabriel can continue his development, he'll surely ascend to the top of the Browns' receiving corps. Whether that can translate to a significant amount of fantasy points remains to be seen.

Overachiever Potential: ★★★☆☆
ADP: Undrafted

Jacob Tamme, TE, Falcons

Tamme had two notable seasons, which history wrote off as Peyton Manning creations. Manning loves his tight ends and Tamme just happened to be on the receiving end of his passes. Now playing for his third team, the veteran tight end is making some noise at the top of Atlanta's depth chart. Julio Jones will be a target magnet, but with Roddy White on the decline and a lack of other options, Tamme could see a decent amount of volume this season.

Overachiever Potential: ★★★☆☆
ADP: Undrafted
