I'd say go with Graham and Starks.
Even though Starks splits carries with Grant, there has not been a single game in which Grant gets more touches than Starks, be it in running plays, or passing plays. It just never happens. Sometime down the season, I'm sure Starks will be named starter. Also, that horrid STL run defense.. my God, GB is probably going to run it a lot just to waste some clock, since they'll be able to score easily.
Graham also has a favorable match up, and TB will want to keep NO off the field as much as possible to prevent explosive plays, which means Graham will see some work.
I am a Best owner myself, and I am very hesitant to start Best. He hasn't proved himself against run defense like that of the 49'ers, so I'm just not sure about him.
