4. He makes the QB better
I don’t care if the Broncos’ quarterback is Case Keenum or a rookie, having Antonio Brown would make whoever is playing that position better.
Especially if he’s working in tandem with Emmanuel Sanders, there are not many cornerbacks capable of covering either of those guys one-on-one for an extended period of time.
If your quarterback has to get rid of the ball quickly, Sanders and Brown can get open quickly. If your quarterback needs to be bailed out on an ‘iffy’ 50-50 pass, Brown can bail him out.
Everything Brown brings to the table makes the quarterback’s job easier. Not only that, but his presence makes the running game better. Teams didn’t have to respect the Broncos’ passing game this year, especially after Emmanuel Sanders went down, because the receivers haven’t fully developed yet and were struggling to get open quickly.
Combined with a poorly coordinated offense, that was a recipe for disaster.
Brown makes everyone around him better because he commands attention, and even when he commands attention he’s an effective playmaker. He’s one of the best receivers I’ve ever seen at making plays in traffic or in seemingly impossible situations.
