Cornell Powell probably has the lowest floor on this list, but given the right set of circumstances has the highest ceiling. He's a high risk even in redraft leagues, so what I advise is to keep tabs on him for the first 3-4 weeks to see if he's getting his reps in, then pick him up after you see he's trusted with some touches. The Kansas City Chiefs took him in the 5th round. And if he gets going, he can be the steal of the draft in your leagues. Not only is Powell in the best offense in the NFL that loves to throw the football, but his path to being a starting WR is also highly possible.
He has to beat out Demarcus Robinson or Mecole Hardman for a starting position, both very poor route runners with stone hands. Cornell Powell, on the other hand, is a great route runner with safe hands and an absolute unit at 6 foot 210 pounds. Meaning, he can play in 2 WR sets due to his size and skill to block. With either Travis Kelce or Tyreek Hill facing double teams on every down, Cornell Powell has all the makings of having a breakout season. Some say that because Powell played in Clemson, he is a product of Trevor Lawrence, but now he can go ahead and gladly be a product of Patrick Mahomes.
