The Miami Dolphins have signed Courtney Anderson to battle David Martin for the starting tight end job.  Anderson played in all 16 games (11 starts) for the Raiders last season and he caught 25 passes for 285 yards (11.4 avg) with 2 TD grabs.  Anderson has played 3 years in the NFL and he has played in 39 games (28 starts) and he caught 62 passes for 763 yards (12.3 avg) with 6 TD grabs.  This was a good move for the Dolphins who want to have the TE be a big part of the offense in 2007.
