The St. Louis Rams have signed 31-year old fullback Dan Kreider to a 1-year contract.  Kreider is the classic blocking fullback who should be able to give Brian Leonard a breather from time to time.  He also could replace Leonard at fullback to free him up to play tailback if anything happens to Steven Jackson this season.  Kreider played in 10 games for the Steelers last season and he carried the ball 1 time for 2 yards.  He also caught 1 pass for 15 yards last year.  If Kreider gets playing time for the Rams he should help out the running game big time because of his blocking.  Kreider has now played in 113 games in his NFL career and he has carried the ball 31 times for 144 yards (4.6 ypc) with 2 TD runs.  He also has caught 60 passes for 471 yards (7.9 avg) with 2 TD grabs.  Kreider is basically just a solid, hard nosed player who makes every team he plays on better.  So, this was a good move for the Rams.
