So the best winning is boring? Then either nobble them as per Obree [handicap, or just cap...so that it becomes "like" a competition, and make 'em all ride the same bikes while we're at it, or take a step backwards with technology and prevent radio communication perhaps, and computers, and support] or bring back the dopers, or just allow them to engage in actual combat to take out their rivals. Interesting to note that the EPL was described the same way when ManUtd were canning it and similarly that had money at its heart too...and the kind of hatred that sports fans are so good at, but that didn't last too long...the dominance that is, the hatred remains as a significant attachment for some.
Don't blame Froome/Sky for being better. In other sports a new manner of playing [total football or riding to the numbers for example] occasionally gains the upper hand for a while, then the competition finds a way of combating that [a new formation or different tactics perhaps] and everything is on its ear again. Or more cynically, the money balance/teams/alliances are not fixed indefinitely. You can wait until it finds your Goldilocks zone, or take what you can from it the way it is.
Sky are doing what they're meant to do and are very successful at it. It's up to the others to come up with a way of countering that, either at their own game or using a different method. If nothing else Sky are predictable. The others know what they're facing before it even starts. That's a powerful tool to have when facing a foe. [eg. If you know your opponent at chess is always going to swap pieces, like an early computer game, you can take advantage of that. Similarly, if you're facing off against someone like Luis Suárez, you could dab on a little dark sauce and have a bet each way.
] That the others haven't been able to exploit that yet ain't Sky's fault.
For mine, if you find it boring, blame those who can't compete rather than those who can...or perhaps expand your vision.
There's so much more going on in a grand tour that I can't help feeling that those who can only be made happy by the "right" person winning the overall comp are missing a hell of a lot. There's a race every day [barring rests], for weeks. Sky/Froome don't win them all, or even try to. There's the sprint and climbing jerseys to fight over. Even if the winner is a foregone conclusion a week or more out, surely there's interest in how your favoured team/riders will progress or what misfortune befalls them? For example, this year Porte was a realistic GC hopeful. An untimely early flat, a fall or two, a crash into a motorcycle ffs, and you're still left wondering if he's able to mount a challenge, and even once that hope is all but gone, there's still a podium place within reach. Or nonspecifically, how can anyone not be impressed by descents in the wet at breakneck speed? I have to remind myself to relax every few minutes. Or back to specifics again, how impressive was it that Sagan can put down so much power that he's spinning his back wheel at close to 70kph at the very last throw!!! [Oh I know it was over a crossing that looked damp but I'm not looking to tear down heroes
]. Or what if Froome had fallen AND injured himself badly in the last couple of days? That's all it would have taken. Would that then have made it exciting again, or kinda sad/comical in a good ol' Steven Bradbury way? Would all those who'd tuned out have come running back in again, or would turning up for the last scene have blown their chance of enjoyment yet again?
Finding such a massive endeavour as the TdF boring is like complaining that life is boring. Sure, it can be if your focus is limited. It's nowhere near if you seek out things that aren't, even what might initially seem like small things. You can sit in a doctor's waiting room moaning about the wait, or pick up a National Geographic and learn about something that you might not have known. At least some of the responsibility for that is yours. Believe it or not, even entertainments like bands or movies or sport do not have you as their specific and sole priority. They might be happy to have you along and even hope you enjoy the ride, but they usually have bigger fish to fry. You can often still find things worth taking away from them though, usually without much effort at all. Or don't. The choice is yours.
Priorities are another kettle of fish altogether. Not everyone gets time to watch as much as others, but that TdF, boring? I find that difficult to relate to. Perhaps I'm just easily impressed.
