Marlon Wayans -- JPP Could Blow Up On 'Live' ... Just Like The 4th Of July

He said it ... not us.

Marlon Wayans says Jason Pierre-Paul's career could be about to EXPLODE ... 'cause according to Marlon, the NY Giants star should replace Michael Strahan as Kelly Ripa's co-host on 'Live'.

It's the question everyone is asking right now ... who's gonna step and replace MS now that he's moving on to the (much, much) greener pastures of "Good Morning America"?

We got Marlon leaving The Nice Guy out in West Hollywood and asked who he thought would be good for the gig ... and the funnyman got EXTREMELY FUNNY about the list of ex-NFL guys he thinks could hack it.
