I'm going with Martellus Bennett as the New York Giants newcomer who will have the biggest impact.
It's pretty simple. The Giants needed a tight end, so they signed Bennett. He was sitting behind Jason Witten back in Dallas, and now he has a chance to shine for the G-Men.
Eli Manning tends to get the best out of his targets lately; if you disagree, take a look at Victor Cruz, Hakeem Nicks, Mario Mannigham or Jake Ballard's stats last year.
Eli gets it done, and it's time for Bennett to shape up and put his off-the-field issues to rest. Tom Coughlin fines people for being five minutes early to meetings (not early enough,) so you better believe he's not putting up with anything from Bennett.
Keith Rivers, David Wilson, Adrien Robinson and Rueben Randle all have the chance to make a bigger impact than Bennett.
I would have absolutely no problem seeing this happen, but as of right now, I'm banking on Bennett to have the biggest impact.
Unlike most of the newcomers, he'll be starting. He also shadowed one of the best tight ends in the league right now for a few seasons.
Apparently there's issues with his weight, but I don't really buy it (h/t Jorge Castillo, The Star-Ledger). There's a lot of time between now and Week 1 when the Giants get to play Bennett's old team.
So unless he likes seeing some serious bench time, I except to see him in shape and ready to play some great football.
Let's be real, who doesn't like getting a chance to beat up on your old team a little bit?
It's even better when that team is the Dallas Cowboys.
