Stefanidi, obviously yes and could win gold (even less than 4.90 m). No one is a real threat only Ryzih and Bengtsson are the good ones in the pool.
Papachristou may win gold if Mamona or Gerrish don't jump better than 14.75 m.
Filippidis is an enigma, he can be good or he could fail badly. My high hopes is on Karalis and he is just 17.
