The Minnesota Vikings have signed Gus Frerotte to back up Tarvaris Jackson this season.  Frerotte played in 8 games for the Rams last season and he completed 94 of 167 passes (56.3%) for 1,014 yards with 7 TD passes and 12 interceptions (58.3 QB Rating).  He also carried the ball 6 times for 3 yards (0.5 ypc).  Frerotte has now played in 137 games in his NFL career and he has completed 1,521 of 2,805 passes (54.2%) for 19,134 yards with 102 TD passes and 91 interceptions (74.3 QB Rating).  Frerotte has also carried the ball 177 times for 308 yards (1.7 ypc) with 5 TD runs in his career.  At least Frerotte is a capable NFL QB which the Vikings didn’t really have on their roster last season so look at his signing as a big upgrade.
