The Bills have signed 30-year old running back Dominic Rhodes to a 2-year deal.  Rhodes played in 15 games for the Colts last season and he carried the ball 152 times for 538 yards (3.5 ypc) with 6 TD runs.  He also caught 45 passes for 302 yards (6.7 avg) with 3 TD grabs for the Colts last season.  Rhodes will compete with Fred Jackson to see who starts at tailback while Marshawn Lynch is serving his suspension.  Rhodes has now played in 96 games in his NFL career and he has carried the ball 777 times for 3,114 yards (4.0 ypc) with 26 TD runs.  He has also caught 146 passes for 1,021 yards (7.0 avg) with 4 TD grabs in his career.  Early on he also was a returner for the Colts and he could help out the Bills in that capacity if the need arises.  Rhodes has returned 135 kickoffs for 3,122 yards (23.1 avg) with 2 TD returns in his career.  This was a good move for the Bills.
