This could get awesome!!!

Now that Ryan Fitzpatrick has reportedly re-signed with the Jets, Brandon Marshall is getting all sorts of cocky ... betting HIS PORSCHE that he'll have more receiving yards this year than Antonio Brown.

The NY Jets wide receiver took to social media to issue a very expensive challenge to his Pittsburgh Steelers rival.

"If you have more receiving yards than me, I'll give you the Porsche ... if I have more recieving yards than you, then you gotta give me the Rolls-Royce."

So far, no response from Antonio ... but you can't imagine he's gonna back down from this!

Game on!
