Does Size really matter when it comes to the '50/50 Receiver'?

A lot of people bring up a player's height & weight as a reason as to why they are not capable of being 50/50 receiver. But I think players like Steve Smith Sr. and Tyreek Hill prove otherwise. How do you guys feel about the 50/50 receiver conversation going on in the #RavensFlock ? Do you feel like you have to be 6'2 And weigh 220lbs?

What do you guys think? Do you think a player has to be over 6ft in order to be a 50/50 receiver?
