Things change between January and the draft, it's not outlandish to say that a guy might slip one or two spots depending on how the next six months pan out. People jump up and people slip every season.
Word, it's too early to tell right now. I'm definitely receptive to offers this year, like I was last year. I think last year was a deeper draft though, so I'd rather keep a top 3 pick than trade down for multiples this year.
