So the tweet in the OP says the bills want to move up from 9, and dolphins want to move down from 19...so the bills want to pick sooner than 9? Also, why even mention the bills and dolphins in the same tweet. Makes it sound like they would be good trade partners...
Yes, the Bills want to move up into the top 5 picks so they can draft one of the top players in the draft. Miami wants to move down so they can get extra draft picks.
