Mike Wallace (No. 11)
The prize of Miami's 2013 offseason is expected to have a huge impact on Miami's offense. The hope is that with Wallace's speed and Tannehill's big arm, the Dolphins will create plenty of offensive fireworks during the season.
Brian Hartline (No. 82)
The Dolphins would love to see Hartline replicate his 74 receptions for 1,083 yards from 2012, which he could definitely do. However, an increase from one touchdown is what the Dolphins really would like to see out of Hartline now that he will likely not get double-teamed thanks to the Mike Wallace signing.
Brandon Gibson (No. 10)
Gibson showed a lot of promise with St. Louis last season, but was far from consistent. His numbers as a Ram scream No. 3 wide receiver, however, you will notice that most of those numbers came in only three games (including one against the Dolphins). Throughout mini-camp and OTA's, it appeared that Armon Binns was a threat to take Gibson's spot as the third receiver. However, training camp will likely tell a better story to help differentiate between the two.
Armon Binns (No. 19)
Binns has impressed many during OTAs and mini-camp with his improvement over last season, and should make it onto the final 53-man roster if he can continue that progress into training camp. However, it will get tougher for him, as during OTAs he mostly worked against second- and third-unit defensive backs, but now will be working against the first-team defense.
Rishard Matthews (No. 18)
The second-year receiver out of Nevada teased Dolphins fans with his speed when he saw the field last season, however, at times he appeared to have issues holding onto the catch itself. At best right now, Matthews is looking at competing for the fifth receiver job. However, it will be a tough battle for him to hold onto the roster spot.
Jeff Fuller (No. 14)
After going undrafted out of Texas A&M in the 2012 NFL Draft, Fuller reunited with his head coach and quarterback with the Dolphins, spending last season on the Dolphins' practice squad. Fuller leaves a lot to be desired when it comes to speed, and will barely fight for a roster position through training camp. A second year on the practice squad, however, might not be out of the question.
Brian Tyms (No. 85)
Like Fuller, Brian Tyms spent last season on the Dolphins' practice squad, and will be looking to earn a roster spot in 2013. If he continues to show the improvement the Dolphins saw last season, there's a good chance that Tyms could wind up on an NFL roster, even if it's not the Dolphins' roster. With the speed that Tyms has, there will always be a market for him.
Marvin McNutt (No. 87)
Marvin McNutt is in a position to make noise during the preseason, especially since he will be working with his wide receivers coach from Iowa in Dolphins' receivers coach Ken O'Keefe. His size and speed are what the Dolphins tend to look for in a wide receiver, however, like the rest of the wide receivers from four on down, he will have to shine in the weeks leading up to the start of the season to make it on the Dolphins' roster.
Jasper Collins (No. 83)
Collins comes from Division III Mount Union, where his impressive numbers made him the only Division III player to earn an invite to the East-West Shrine Game last January. With a 4.49 40-yard dash time and plenty of potential, he's a possible practice-squad player this season for the Dolphins.
Chad Bumphis (No. 16)
Bumphis has the highest profile of Miami's undrafted free agents coming from Mississippi State, however, while he does show promise and potential, he will be neck-and-neck with Jasper Collins in terms of which player will likely wind up on Miami's practice squad.
