Here's video of Antonio Brown working on deep balls with Washington QB Dwayne Haskins ... and we gotta say, the two certainly have chemistry that could carry over to FedEx Field!!!

Check out the clips Brown posted from the training sesh ... there were some 50-yard dimes that had people going crazy over the completions!
