He's going to tear it up with them. Sure the Pats may have other options, but none of them are on Antonio Brown's talent level, and let's not act like he didn't get his fair share of touches while sharing the ball with the rest of Pittsburgh's weapons (JuJu, Bell, etc) also. The Pats are not going to be this ball control run the clock offense like everyone thinks they are. That's what everyone said when they had no AB, Gordon, etc. They are going to be one of the most well-balanced, unpredictable offenses in the league and everyone is going to eat. And AB fits the offense like a glove and is getting a QB upgrade. If anything, I see other guys like White and Gordon losing some of the target share to accommodate AB, not vice versa. I'd be surprised if there's any statistical drop-off at all.
It's a nightmare scenario for a Jets fan and I'm not looking forward to it one bit.
