Last year Prescott was the tenth quarterback in fantasy and he only had Amari Cooper for half the season. With Cooper there for the entire year, Prescott has top-5 upside. Dak also comes with great rushing upside, as he has had six rushing touchdowns in each of his first three seasons. The reason Prescott isn't ranked higher is Ezekiel Elliott's holdout. If Zeke misses time, defenses are not going to focus on stopping the run and Prescott won't be nearly as good. In the six games Zeke was suspended in 2017, Prescott only had 1,146 yards, 5 touchdowns, and seven interceptions. Over the course of an entire season that ends up becoming only 3,056 yards, 13 touchdowns, and 19 interceptions. Overall, Dak has top-5 upside and is relatively safe if Zeke plays, but if he doesn't Dak won't be a starting-caliber player.
