This is a matter of perception....if he's ahead of schedule, he would have to be practicing at full speed in 2 weeks and able to play in the Preseason Game #3, which is the only likelihood of snaps received for Graham or Rawls. As much as I feel Graham is ahead of schedule, that doesn't mean he's on the field Week #1.....I don't see the need to rush him back and on the field in less than 30 days from Preseason Game #3, which is what it would truly take for him to make the final active roster and not on PUP to start the season.
These preseason games are really better scenarios to get Verrett, Willson etc on the same page and to get kids like Collins, Prosise and others acclimated to NFL life.
I view Graham as a player that buys a player like Paul Richardson or another young player a chance to be active the first 6-8 weeks of the season and see what injuries cause the roster to be reshuffled and Graham being that addition "at the trading deadline", that somehow seems to be a very popular/non-existant item for NFL teams and GM's. Graham is the only "piece" that seems to fit that veteran player that can add a dimension to an offense. I think the faster we get players like Prosise and Collins and Rawls with the WR's clicking, it should open up the TE position for Verrett to thrive. At that point, it becomes using Graham or Richardson (if he survives camp healthy) to see what piece can be added for a stretch run, when we visit Foxboro, Lambeau and host teams like Carolina, Arizona etc....
