what about her in the other elements?
her defence,block, rate of mistake etc ?
In my opinion Egonu is the most dominant and powerful spiker in the world right now. Her jumping skills and the power of her arm are probably even superior than Hooker's... Her defence sucks, and rate of mistake also needs an improvement, but her physical skills are so incredibly devastating that she can definitely be considered already a world-class OPP at the age of 18 years old.
Of course, if she signs with a top team next season, it would be wise not to put too much pressure on her by hiring also an experienced OPP who can enter whenever she needs some rest, but I have no doubt she is ready to play for a top team. At list four Italian top teams are chasing her, but Conegliano seems to be the one with more chances..
