Fernandez injured his back in March 2009, when he was fouled pretty hard by Ariza. it's not that he has a bad back in the mold of Tyson Chandler.
he likely didn't get the right treatment after the injury and started to play again way to early. he played thru a lot of pain when last season started and still did pretty well during November. (shooting 40% 3s). then the doctors discovered that some bone material or whatever put pressure on a nerve. he underwent a microdiscectomy, first they thought he will be out for 3 months, but he came back after 5 weeks. likely to early again, maybe Portland forced it a bit because Roy was out in January either and Blazers didn't want to lose track on the PO.
however, there was a reason that explains his struggle last season and that surgery isn't something that couldn't be totally healed with patience and the right treatment.
btw. character and the "Diva" reproach....
people constantly ignore that no other Euro player has ever left that much money on the table, when Fernandez agreed to come over on a rookie deal. no, he didn't play the 3 years in Spain for the best contract Barcelona has ever offered to a player and then join the Blazers for much more money than a rookie contract. he came immediately. and we won't ever know what the Blazers promised, but let's assume they promised a pretty prominent role on the team.
so yes, he does have some rights to be disappointed, especially when he feels the coach and team didn't treat him right during the injury. and don't forget, they also traded away his best friend Sergio Rodriguez, one of the major reasons why he came to Portland on such a bad contract. (Sergio was also the player, who perfectly introduced most of Rudy's 3s during his rookie season. something neither Roy nor Miller did the following season)
ok, sorry. to many words on this topic. just my reaction to all the clueless assessments about him.
mark my words: one team (Celtics ?) will be very happy with him and in some months we will have several threads how the Spurs could miss out on the opportunity to get Rudy. likely from the same people who now downplay his abilities.
