Before we talk about how Miami's offense is a lock to be improved, keep this in mind: the Dolphins' leading rusher from 2012 is a Detroit Lion, the player with the most touchdown catches last season is a Kansas City Chief and their second-leading receiver from last season is now a Cleveland Brown.
So yes, the Dolphins gained a lot during this offseason. But they did lose some as well, and there are questions in terms of who will be playing where and how much playing time will they get, especially among the wide receivers and tight ends.
Miami's top two receivers? That's practically set in stone with Mike Wallace and Brian Hartline as your number one and number two options.
Number three looks to be a battle between Armon Binns, who performed well during OTAs, and free agent acquisition Brandon Gibson who seemed to disappoint during said OTAs. Binns will likely wind up at the four spot, but so far has been a challenge to the three.
Meanwhile at tight end, Dustin Keller is likely the starter as well as a slot receiver when need be, but it will be interesting to see the competition between 2012 third-round pick Michael Egnew and 2013 fourth-round pick Dion Sims.
Egnew has the edge due to being in the NFL for one year, but Sims seems to be the more complete player. It's definitely a competition worth watching.
More important than these training camp battles though will be how well the winners of said battles perform once they win their jobs. That remains to be seen.
