What's funny is the only good drawing cards Diaz has been in was GSP and Silva.
Penn v Diaz 280,000
Condit v Diaz 400,000 (not bad/not amazing plus was first WW title fight not including GSP. Both fighters were interesting match ups for GSP. Promoted by UFC prime time and was second lowest draw from ppv promoted by prime time)
GSP v Diaz 950,000 Big rivalry plus GSP is a big draw
Silva v Diaz 650,000 Silva return fight.
Also Robbie wasn't much of a draw. Even though his fights were great he never drew over 450,000 (UFC 189 excluded due to McGregor) so I doubt 201 would have drawn much considering casual fans probably losing interest after 200. So safe to say Woodley won't be much of a draw.
Unless they get on 202 and promote as the Diaz brothers I doubt Woodleys getting a huge pay day from it
