Now I don't know what to think about what McCarthy said. More than one way to translate what he means. We've seen Pollard and Zeke on the field at the same time. So working together is nothing new.
The reports over and over again are that we are going to have them on the field at the same time. Whether we actually do it is another thing. But the evidence seems to indicate it. I do think Dallas doesn't want to completely show it's hand on this, but it has had Pollard doing a lot of receiver training this offseason. I think he's going to be out there regularly with the offense, taking or faking jet sweeps, catching WR screens, motioning into the backfield, etc., with Zeke at RB. Makes sense to me to get our biggest offensive threats on the field, and they are Lamb, Elliott, Pollard and Schultz.
Of course, again we have to see Moore/McCarthy actually do that, but there's been a lot of indications that they plan on it. Including what McCarthy said here.
