If Nicky starts talking .... in the press what do you think possible future employers are going to think about him. Sponsors dont really like riders that are going to slam their team and possibly their product by association. I also know that Nicky is real big on being a positive guy. Kind of that positivity breeds positive things mindset. The mugello race has for Nicky was similar to how the season has gone for Marco, the bike is having problems and the rider can not ride through them.
I dont know what Nicky or Marco are dealing with, but I know from my experience that there are certain kinds of problems that a rider can ride around and some problems that no matter what cant be ridden around. Nicky is a guy in a unique position because his ability to either point and shoot or ride smooth and higher conerspeed will allow him to ride around more problems than a lot of riders. But some problems are almost like cutting your legs out from under you. Not to mention, .... happens some times in the middle of races or whenever that makes any adjustment too late. Who knows, a tuning screw could have fell out of his rear shock because some mechanic forgot to safety wire it and it would not stay without the wire.
Marco's problem seems to be completely engine management issues.
