They’re best paired together IMO two completely different receivers
Depends on what else you have and what you like to do with your passing game. I'm very much a controlled passing game. A 10 play drive is typical for me. I use Carmichael, Ward, and Tyreek. Casper is my TE, although I may move away from him soon. One or two times a game I can get Hill open on a streak. I've not had that with any other receiver as consistently.
Quick answer is Megatron...but there is always a "depends". Johnson is far more balanced and rounded than Hill...Johnson can serve as a great WR1 in any passing scheme, and is also great when you wanna run. In a spread offense where you are throwing the ball 90% of the time...Hill may be the better choice in the slot. Now...Johnson could also fill that roll, but is not as slippery as Hill. For me...I see no case for Hill, but...maybe Hill can return kicks better.
Who is the better option? Just trying to get the opinions of those who have used them.
