When has Vale raced around in dead last position? Vale finished 2nd in the championship last year on the Bridgestones.
Lorenzo has trouble adapting this year, that's his problem. It's not a magic tire that's specifically made to hurt Lorenzo. If Rossi was struggling more this year, you'd claim it's because he sucks and is washed up. But whenever Lorenzo fails to perform, it's because of something behind the scenes that has been put in place to hurt him. Because you know... Lorenzo is a perfect rider with no flaws.
You are not helping yourself. People who said Valentino was old and washed up in 2013, which didn't include me btw, were clearly wrong, but if so to what other than an unsuitable tyre do you attribute him being rather uncompetitive with the other 3 riders of what were then the only 4 competitive bikes in that year? We also have seen Jorge win 3 races rather well this year in favourable conditions for the remaining Michelin tyres which suit his riding style, and be dominant in pre-season testing on the particular Michelin tyre which suited him even more but had to be withdrawn because it was unsafe.
I doubt there is a specific tyre conspiracy against Lorenzo this year either (not so sure about Stoner/Honda in 2012, and also have my doubts about Stoner/Ducati in 2008), but it is hard to dispute that Michelin have stuffed up, with their soft dry tyre having to be withdrawn as above, their soft wet tyre delaminating unpredictably rather than just wearing out as the preceding Bridgestone wets did, and also multiple unpredictable front tyre washouts in general for a variety of riders early season. Another rider also usually near the front of the field in Dani Pedrosa has been fairly uncompetitive which looks very likely to be tyre related as well.
In recent races it is starting to look as though, mostly through sheer blind luck imo, Dorna have chanced this year on a more even playing field. To the extent this is due to the control ECU I will give them credit, but not for the Michelin tyre lottery.
In general however in the control tyre era previously that rule has neither leveled the field nor reduced costs, which were its purported aims, and Dorna has been indifferent to the effects of unsuitable tyres not just on individual riders but on multiple entire marques. I don't deny that Lorenzo is flawed in being overly dependent on suitable tyres (mainly in more recent seasons) and that Stoner to a lesser extent was also tyre dependent; I recall suggesting on here perhaps injudiciously when he was looking dominant on the Honda that taking away his preferred "hard" tyre was perhaps the way to stop him.
The basic question for me remains, as it has for 9 seasons, what is wrong with having tyres which suit a wider range of bikes and riders?
Whether the tyres have been manipulated with malice aforethought or Michelin/Dorna are just incompetent, your boy remains screwed in any case, since any tyre which suits him also suits MM, and it looks as though the best and most versatile rider in MM, who still comparatively thrives even when he makes an error in his tyre choice, will justly win the championship.
