Diaz vs. Benson is tied if you include WEC bonuses.
Only one I can think of...
Diaz = 10 UFC bonuses
Benson = 3 WEC bonus + 2 UFC bonuses
Total = 15 bonuses
Forrest/A.Silva have a combination of 18
Forrest = 5
Silva = 13
quite the impressive feat for JLAU/Miller considered though
Assuming you're right about Diaz, Cerrone has 10 including WEC, as well. But I'm just counting now, probably was quite a few even a year ago.

They didn't have 18 when they fought though.
Lauzon/Guillard would be up there too.
