honestly the scout reports I've seen make me like Nabers in most aspects, but that catch radius and route running favours Harrison for being an early producer.
His catch radius is soooo impressive. the one play he was running ball thrown behind him and he bent his body, reached back with one hand and brought in the ball. surprised the hell out of the DB who thought he had an easy INT. and the most impressive part is Harrison didnt even need to slow down. he turned it upfield right away. Most impressive thing I've ever seen.
I will say Nabers due to his speed seems to gain better separation. but if the ball is behind him he cant do what Harrison did on that play.
so if you have a pin point passer, Nabers is likely the preferred guy. if you have a QB whose accuracy is lacking some, Harrison will actually make up for that with his catch radius and ability to adjust to the ball.
I do think Harrison is a nice match with Kyler Murray. and I am expecting good things from him in his rookie year.
Nabers is tougher to figure. Danny dimes had a reputation of putting the ball where it needs to be (thus the nickname dimes) but as a pro he hasnt been that good. part of this is due to an inferior line for sure. hard to be accurate when you have to throw early with a person in your face. but if they can find a way to protect him long enough Nabers could do well here. Thing is... if New York Bails on Danny Dimes then we are looking at breaking in a new rookie QB and that hinders Nabers long term. (if you are picking for dynasty)
so if I had to bet on a rookie season I'm betting on Harrison. but I assure you both WR are likely gonna have long and productive careers.
