NY Jets Coach Rex Ryan -- Our Starting QB Will Be ...

TMZ just spotted NY Jets head coach Rex Ryan at Newark Airport in NJ ... and we asked the million dollar question -- who will be the next starting QB for the NY Jets ... Tebow or Mark Sanchez!?!?

And BTW ... Rex actually answered.

At first, it sounded like he said, "BOTH" ... which made sense because there are rumors that the team would run a wildcat offense ... which usually features 2 QBs.

Upon further review ... we realized Rex was saying, "Bo" ... but not Te-Bow ... Bo ... as in NY Jets starting nose tackle Sione "Bo" Pouha ... a 6'3", 325-pound beast.
