Fumbling Cowboys

I ve lost close to 10 game because of my favorite team butterfingers. everytime i try and milk the clock one of my backs or Wrs choke and end up fumbling the football , is this just me or do other Cowboy user having this problem also.

Felix jones has let me down once or twice.. but I'm a religious holder of RB so no other Cowboy has fumbled or really dropped a pass for me.
