New York Giants
The Giants have been a natural trading partner for the Steelers over the last couple of years. Their owners are both historic in the NFL and even are related by marriage. See the movie “Girl with a Dragon Tattoo” with Patricia Rooney Mara. Rooney is the Steelers owner and Mara is the Giants owners. The Steelers have traded Brad Wing and Ross Cockrell there; so, it is likely that the two are familiar with trade talks.
The Giants are desperate for any weapons on offense. They lost Odell Beckham Jr to a season-ending injury and now have little weapons for Eli Manning.
