Interesting blurb in PFW regarding David Martin... "TE David Martin may have started for the Dolphins in 2007, but word out of South Florida is that he’ll have to fight to merely keep a roster spot in training camp. Newcomers Anthony Fasano and Sean Ryan and holdover Justin Peelle could end up being the team’s TE corps."

IMO, solid contributions from the TE and occasional Fullback positions will be difference makers with both supporting a youngish line, and youngish QB's in pass protection, and to allow the studs (Ronnie and Ricky) to do their thing.  Also adding reliable hands to a youngish group of receivers.
