It's a thought. Probably depends on how bad either side burned bridges during the trade. And money of course.

I always loved Graham's intensity. Just didn't like Bree's propensity to throw to him so much.

I don't see it happening personally. But weirder things have happened. He was much better here then he is in Seattle. Which seems to be case with almost all offensive players that leave NOLA.

Intensity is really not a trait I would use describing Graham.
If he's cheap why not. He's familiar with system and has to be an upgrade over what we have. I agree about the burned bridges part. Didn't he say something on twitter about happy to be leaving Saints? Could have been someone else telling him that he should be. I can't remember.
Anyway I don't think Seattle ever used him to his strengths.
