I think to say get real is a little aggressive. Yes, Schefter usually breaks Pats* news. Yes, the league is aware of trades when they are made. But, maybe a trade isn't official depending how a visit from Gronk to Dallas.
You are probably correct, but, there are always possibilities things are 100%, so, get real is an aggressive statement that is not open minded.
EDIT : and yes flying commercial most likely suggests Jerry Jones isn't trying to lure Gronk.
