Fantasy Upside
Rookie Zay Jones didn't have much value entering the season, but the Sammy Watkins trade changes things. Now, Jones might have to grow up quickly. He does have a good pedigree as the Bills chose him in the second round and he was the fourth wide receiver taken overall. Opportunities will be there and maybe QB Tyrod Taylor finds chemistry with Jones quickly.
Fantasy Downside
Rookie wide receivers are very green. For every stud rookie wideout you see emerge in the NFL, you see four or five guys who are duds or need two or three years in the league to make an impact. Also, Buffalo is a run-first team who will not throw the ball 40 times a game. Opportunities might not be plentiful for any of the Bills receivers, so even if Jones gets snaps, the numbers might not reflect the time on the field.
2017 Bottom Line
Jones is talented and might become a good NFL receiver someday. But I don't think that's going to happen in 2017. He might be worth taking a flier on in the late rounds, but even his ADP in rounds 16-17 is a bit steep. If it's a keeper league, then maybe, but he will likely not return much value in 2017
