The San Francisco 49ers have replaced Shaun Hill as the starting QB as they will go with Alex Smith for the time being.  Smith played in his first game of the season last week against the Texans and he completed 15 of 22 passes (68.2%) for 206 yards with 3 TD passes and 1 INT (118.6 QB Rating).  He also carried the ball 2 times for 16 yards (8.0 ypc) last week.  This will be an interesting move as Shaun Hill was not playing that poorly this season.  Hill started the first six games of the season for the 49ers and he completed 87 of 155 passes (56.1%) for 943 yards with 5 TD passes and 2 INTs (79.6 QB Rating).  He also carried the ball 8 times for 70 yards (8.8 ypc) this season.  Smith has a stronger arm than Hill and this is the best talent he has ever had around him so he will have no excuses for failure this time around as the starting QB.
