Just watched a bunch of film on the guy. Yeah I know, they're called highlights for a reason. But, I can see why they like him.
I know Gus/Chad won't be running the same offense, which from all accounts was wide open. The article I read said King was usually the 3rd or 4th option, so if he had 54 catches, they undoubtedly throw it all around the field. He lined up in numerous positions, but mainly either coming in motion out of the backfield, or in the slot. Ran all types of routes, but one of the most impressive things was how well he blocked. He was physical at the point of attack and really got after people on bubble screens and out in front of runs down field. Not blazing fast (On film, anyway)but keep in mind that he is 6'5" and very athletic.
Also keep in mind, I don't know my ass from a hole in the ground when it comes to evaluating film. I just know Daddy like.
