A crowded backfield and oversupply of hands in the receiving unit may force the Miami Dolphins to trim some of its roster through trades.

Football Nation has learned that both receiver Mike Wallace and running back Lamar Miller could be casualties of the recent moves made by new team general manager Dennis Hickey. Wallace was signed as a free agent last season from Pittsburgh in an effort for the team to have a true No. 1 receiver on the field. Wallace finished second in catches this season to Brian Hartline and had issues at times with consistency and timing – the result of quarterback Ryan Tannehill bot being able to move around in the pocket as freely as he would have liked. The Dolphins led the league in quarterback sacks with 56 last season.

According to sportsworldreport.com, the Dolphins have made a number of moves this offseason to improve on offense and while a Mike Wallace trade may not be the best move to help that, the team could look to deal him along with Lamar Miller for draft picks or need areas if they feel that Knowshon Moreno and Jarvis Landry are good enough to be starters, as Ryan Tannehill needs a more consistent offense.

Whether or not that is enough to warrant trades is a decision the organization has to make. The team also has Daniel Thomas and Mike Gillislee under contract to provide depth in the backfield.

Wallace was known as a "me first" receiver before he came to the Dolphins and if that continues to play out, he could be on his way out of town next year. The team brought in Knowshon Moreno and after he set career highs with the Broncos in receptions and yards as well as rushing yards, he could be a nice weapon out of the backfield.

The rushing game ranked 26th in the league last season and even five spots up could be huge for the Fins in 2014 after Thomas and Miller struggled during the season.

The fact the team made several offseason moves in free agency and in the 2014 Draft to secure offensive line help means the team will be committed to a balanced offense this season. The only starter from last season who is expected to start this season on the line is Pro Bowl center Mike Pouncey.

The online story also explained that Tannehill needs better blocking to continue his development, as he was running for his life for most of last season while dealing with the porous offensive line. The team drafted Ja'Wuan James in the first round and also drafted a tackle in the third round and this is on top of the move they made to sign Branden Albert in the offseason. Those additions should greatly help the offensive line and Tannehill and it also could give the rushing attack a nice boost.
