Israel should defend his title a few more times as should Jan - no more jumping up for super fights till you've defended and cleaned out your division (Granted Israel has mostly done that but a whittaker re-match is in order).
And Jan needs to defend a few times (Reye's rematch at some point, Santos, Glover, Rakic)
And maybe by this time Pereira (Alex) will be ready for the UFC and he can come and KO anyone from 170 to 205 who dares to stand with him.
