It most certainly has everything to do with his size. No way can he sustain an entire season without a bruiser to take the goal line and short yardage carries. Even Barry Sanders was taken out at the goal line and short yardage situations because his body potentially could falter and Gore is nowhere near barry Sanders level. Just take a look at Westbrook or Dunn as well.
Here is a quote from Rotoworld on Gore:

Frank Gore may earn 15-18 carries a game the rest of the season.
According to ESPN.com's Len Pasquarelli, the San Francisco coaches don't believe Gore can handle a full workload, but they want to see how productive he is splitting carries with Kevan Barlow.
