The No. 3 wide receiver has been a source of constant chatter throughout the offseason. There's an intriguing mix of players, including a second-year rookie, a possibly recovered record-breaking college receiver and a wily vet looking to extend his career.

And no one has any clue which one will win the job. The mystery adds the extra ingredient that elevates this battle from merely sustenance to tasty appetizer.

But it isn't a main course. Whoever wins this job will probably see the sixth or seventh most targets in the offense behind the top three running backs and at least one tight end. Last year, Jeremy Ross saw 36 targets and finished seventh.

The early favorite is either Corey Fuller or Lance Moore.

Fuller, the sixth-round pick entering his third year, is the top backup for Calvin Johnson and would allow Golden Tate to slide inside. He stepped in with Jeremy Ross when Johnson was out of OTAs, per Meinke, and has experience with this team and system:

Moore, 31, is the wily veteran who knows the nuances of the offense from his eight years in New Orleans. He's enjoyed a solid performance so far, per Paula Pasche of Lions Lowdown, but it's unclear if he can fend off the younger competition.

Ryan Broyles and T.J. Jones round out the major competitors. The former needs to prove his speed and burst have regenerated after his numerous injuries, while the latter will be practicing with pads for the first time in two years.
