That's where it gets tricky I guess. Where does a TE "line up"? He's far from the first TE to be split wide, and it's not done as a TE playing WR for a snap or so... that's a function of today's TE. So I personally wouldn't look at it like he lined up 66% of the time as a WR but "as a TE" he lined up in the slot 66% of the time.
Mr. Irrelevant, Marques Colston, was drafted as a TE. They moved him to WR. I think this is actually a perfect example against what you're saying.
In addition, all of the crazy examples being thrown out now make no sense. Maybe if these teams decided to (to use one example) call Eli Manning a kicker when they get to the negotiating table, but there isn't a person in the world that would let that happen. I think this also goes against the point you are trying to make. Graham's role didn't just suddenly change. Why wasn't he pushing to be listed as a WR years ago? Instead, it happens at the negotiating table... clear attempt at a money grab.
I think the focus is on the wrong thing here, and what Graham, and the rest of the people on his side, should be fighting for is an evolution of the TE pay scale. Their roles are expanding and more TEs are becoming huge focuses in the passing game, and maybe the salary scale should be adjusted accordingly. I could get behind that more than the claim that he's a WR and should be paid within the WR framework.
