Fantasy Upside
There is no doubt Dez Bryant is one of the best receivers in the NFL and his numbers last year show that. With DeMarco Murray gone and the Cowboys shifting around their running back personnel, Dally may rely more on the passing game in 2015. Bryant has been doing it all from a fantasy standpoint. High number of receptions. High yardage total. High touchdown total. He is a constant on the Dallas offense and will be their most important player on that side of the ball.
Fantasy Downside
Bryant will still put up numbers, but it would be surprising if he matched or exceeded his 16 touchdown total from 2014. Most likely, the Cowboys offense will not be as efficient and score less points this season, which would cut into Bryant's production from the TD angle.
Bottom Line
You really can't go wrong with drafting Bryant. He is going to be the top fantasy receiver some weeks and will be a consistent performer all season. His ADP puts him as a first round pick in standard and PPR leagues. If he falls to the 2nd round somehow, grab him as the bargain of your draft.
